Tips:

With Foxit PDFReader, you can also open an XFDF, FDF, or XDP file which is a data file containing comment or form field information exported from a PDF file. When you try to open an XFDF, FDF or XDP file, Foxit PDFReaderwill attempt to locate the PDF file associated with the XFDF, FDF or XDP file and then open that PDF file with the data filled in. Therefore, make sure that the source PDF file associated with the XFDF, FDF, or XDP file is available with its original file name in case the operation fails.
If Foxit PDF Reader is closed unexpectedly, it will start automatically with all tabs restored on the next startup of your system. (Tip: To make this feature effective, you need to check the Reopen windows when logging back in option in the system’s prompt message when you shut down or restart your Mac device.) If you want to change this default setting,please chooseFilein the Ribbon (orFoxit PDF Readerin the menu bar) >Preferences>General>Application Startup, and uncheckAutomatically restart the application with all tabs restored.

Save a PDF File

By default, Foxit PDF Reader saves the changes to a file every 5 minutes automatically in case of system crash or power failure. If the application closes abnormally before you can save changes to a file, Foxit PDF Reader opens the recovery file automatically the next time you open it. The recovery file contains your changes up until the last time Foxit PDF Reader saved the document. You can change the time interval settings in Preferences > Documents > Save Setting > Automatically save file every x minutes.

After editing your PDF file, choose File > Save (or click the Save button in the Quick Access Toolbar) to save and replace the original file. You can also choose File in the Ribbon > Save As to save the PDF file as a copy in your local disks, ECM servers, or cloud servers.

Foxit PDF Reader allows you to configure the preferred save as location so that your preferred location will be automatically chosen in the Save As dialog box when prompted to specify a location to save a document. To add a preferred save as location, please go to the File tab (or Foxit PDF Reader in the menu bar) > Preferences > Documents > Preferred Save As Location. Then click Browse to select the location, or input the location in the Preferred Save As Location field. If you need to remove the configured output location, just delete the directory path in the Preferred Save As Location field.

Read PDF Files in a Single Tab or Multi-tabs

Read PDF Files in Multi-tabs

By default, Foxit PDF Reader displays multiple PDF files in different tabs in a single application window. In multi-tab reading mode, you can drag and drop a file tab outside of the existing window to create a new window and view the PDF file in that individual window, or move a file tab to any other Foxit PDF Reader windows that are currently open.

Read PDF Files in a Single Tab

You can enable the single-tab reading mode to view PDF files in multiple application windows when double-clicking to open PDF files, which is ideal for reading PDFs side by side.

To enable the single-tab reading mode, choose File in the Ribbon (or Foxit PDF Reader in the menu bar) > Preferences > Documents, check the Always open files in a new window option in the Open Setting group, and click OK to apply the setting. While in the single-tab reading mode, you can revert to the multi-tab reading mode by redoing the steps and unchecking the Always open files in a new window option.

Read Multiple PDF Files in the Parallel View

The parallel view allows you to read two or more PDF files side-by-side (either horizontally or vertically) in the same window. When reading PDF files in the parallel view, you can view, annotate, or modify each PDF file independently. However, the Full Screen Mode operations are simultaneously applied to PDF files that are currently active in all tab groups.

To create the parallel view, do the following:

Open two or more documents that you want to view in Foxit PDF Reader.
Right-click on the file tab of the PDF document that you want to move to a new tab group, and choose one of the following options as needed:
- New Horizontal Tab Group: Display the PDF document in a horizontally parallel view.
- New Vertical Tab Group: Display the PDF document in a vertically parallel view.
Tip: If you are in the parallel view, when a new PDF file is opened, it will be placed in the last active tab group.

To move tabs in the parallel view, do one of the following:
- Directly drag and drop the file tab to the tab group that you want the PDF document to be moved into.
- Right-click the file tab, and choose Move to Next Tab Group to move the PDF file to the tab group that is opened after it, or choose Move to Previous Tab Group to move the PDF file to the tab group that is opened before it.
- If there is more than one file tab in a group, right-click any file tab in the group and choose Move all tabs to the next group or Move all tabs to the previous group to move all the file tabs in the current group to its next or previous group respectively. When all the file tabs have been moved out, the corresponding tab group will be closed automatically.
To exit the parallel view, do one of the following:
- Close all PDF documents to leave only one opened.
- Move all the opened PDF files to the same tab group.
- Close Foxit PDF Reader, and it will return to the normal view when reopened.

        To set reading preferences, choose File in the Ribbon (or Foxit PDF Reader in the menu bar) > Preferences > Reading.
        
        Screen Reader Options
        
        Page vs Document: This preference determines how much of a document is delivered to a screen reader at a time. If a PDF isn’t tagged, Foxit PDF Reader may analyze the document and attempt to infer its structure, which can take a long time for a long document. You may want to set Foxit PDF Reader to deliver only the currently visible page so that it analyzes only a small piece of the document at a time. This consideration will vary depending on the size and complexity of the document and on the features of the screen reader.
        
        Only read the currently visible pages - This option is usually best when using a screen magnifier. It improves performance by eliminating the need for the software to process parts of the document that aren’t visible. When Foxit PDF Reader sends only the currently visible pages of a PDF to the memory buffer, the assistive technology has access to those pages only. It cannot go to another page until the next page is visible and Foxit PDF Reader has sent the page information to the memory buffer. Therefore, if this option is selected, you must use the navigation features of Foxit PDF Reader, not those of the assistive technology, to navigate from page to page in the document. You should also set the Default Page Display option in preferences to Single Page if you choose to have Foxit PDF Reader send only the currently visible pages to the assistive technology.
        
        Read the entire document - This option can be best if you use a screen reader that has its own navigation and search tools and that is more familiar to you than the commands in Foxit PDF Reader.
        
        For large documents, only read the currently visible pages - This option is selected by default and is usually best if you use a screen reader with long or complex PDFs. It allows Foxit PDF Reader to deliver an entire small document but revert to page-by-page delivery for large documents.
        
        Reading Order: Set reading order as appropriate for your assistive software and devices.
        
        Infer reading order from document (recommended): Interpret the reading order of untagged documents by using an advanced method of structure-inference layout analysis.
        
        Left-to-right, top-to-bottom reading order: Deliver the text according to its placement on the page, reading from left to right and then top to bottom. This method is faster than “Infer reading order from document”. This method analyzes text only; form fields are ignored and tables aren’t recognized as such.
        
        Use reading order in raw print stream: Deliver text in the order in which it was recorded in the print stream. This method is faster than “Infer reading order from document”. This method analyzes text only; form fields are ignored and tables aren’t recognized as such.

        Work on 3D Content in PDFs
        
        Set 3D Preferences
        
        Foxit PDF Reader lets you view, navigate, measure, and comment on 3D content in PDF documents. The Model Tree, the 3D toolbar, and the right-click menu of 3D content can help you work on 3D content easily. You can show/hide parts of a 3D model, set different visual effects, rotate/spin/pan/zoom a 3D model, create and manage 3D views with different settings, add comments/measurements to a part of a 3D model, and more.
        
        Note: By default, Safe Reading Mode is enabled, and whether the option has been selected or not, when you open a PDF with 3D content for the first time, a dialog box pops up to ask whether you trust the document to enable/activate the 3D content in it, and you can select an option to trust the document one time only or always trust the document. Selecting Trust this document always in the dialog box also adds the document to the privileged locations, and the dialog box will not prompt next time you open the PDF. See also Privileged Locations. Note that the dialog box does not necessarily pop up when you open a 3D PDF. Sometimes it pops up only when you click on the 3D content in the PDF. When it pops up is determined by the activation settings of the 3D content. And the message displayed in the pop-up dialog box varies depending on your trust settings for Foxit PDF Reader.
        
        Display 3D Models
        
        Foxit PDF Reader provides the Model Tree and various navigation tools and options for you to show or hide parts of a 3D model, turn it around to view it from all orientations, even look at the inside structure clearly by hiding and turning parts around.
        
        When you open a 3D PDF and enable the 3D model, the 3D toolbar appears above the upper-left corner of the 3D canvas (an area where the 3D model appears). The lower-left corner of the canvas shows the 3D axes (X-axis, Y-axis, and Z-axis) that indicate the current orientation of the 3D model in the scene. Note: If the 3D model is not enabled (or activated) after you open the PDF, only a 2D preview image of the 3D model is displayed in the canvas.
        
        Tip: For most 3D-related tools and options, you can find them from the context menu after right-clicking the 3D model.
        
        Show/Hide Parts of a 3D Model
        
        When the 3D model is enabled, click the Model Tree panel in the navigation pane, where you can view the 3D scene structure and the preset views. Check/uncheck the appropriate checkbox to show/hide the corresponding part of the 3D content. You can also click the Toggle Model Tree icon on the 3D toolbar to show or hide the Mode Tree panel.
        
        The Model Tree panel contains three panes: the Structure pane, the View pane, and the Object Data pane.
        
        The Structure pane: The topmost pane in the Model Tree panel. In this pane, you can view the tree structure of the 3D content and show/hide parts of the 3D content.
        
        The View pane: The middle pane in the Model Tree panel. It shows a list of available 3D views associated with the 3D content. You can create and manage 3D views.
        
        The Object Data pane: The lower pane in the Model Tree panel. It displays the information such as properties and metadata associated with an object/part you select in the Structure pane or the View pane.
        
        Navigate through a 3D Model
        
        On the 3D toolbar (or after right-clicking the 3D model and choosing Tools), select a desired 3D navigation tool to manipulate the 3D model.
        
        Rotate Rotating a 3D model allows you to turn it around in the desired direction. Click the model, hold the left mouse button, and move the mouse in the direction you want it to rotate.
        
        Spin Spinning a 3D model turns a 3D model in parallel around the X-axis and Y-axis. Click the model, hold the left mouse button, and move the mouse in the direction you want it to spin.
        
        Pan The Pan tool allows you to move the model vertically and horizontally. Click the model, hold the left mouse button, and move the mouse in the desired direction.
        
        Zoom With the Zoom tool selected, click and drag the left mouse vertically to move toward or away from the 3D model. If you right-click and drag an area on the 3D model, that area will be magnified and fill the document window.
        
        Walk The Walk tool is useful for navigating through an architectural 3D model like rooms or buildings. For example, the 3D model is a two-story building and you can simulate walking through the building. Click and drag the mouse vertically up and down to go forward and backward, and drag the mouse horizontally left or right to turn left or right in the building. The Walk tool maintains a constant elevation as you drag the mouse. So moving upstairs or downstairs in the building is not available for the Walk tool (You need to use the Fly tool instead).
        
        Fly The Fly tool lets you navigate through the 3D model while maintaining the surface orientation, which is useful when viewing an architectural or a landscape model. When “flying” through a model, you are not constrained by the elevation, so you appear to “fly” over an area in a model. With the Fly tool selected:
        
        Click and drag the left mouse in the direction you want to look at. The Fly tool moves the view more slowly (which seems to increase the magnification) the closer you approach an object.
        
        Right-click and drag the mouse does not change the magnification.
        
        Scroll the mouse wheel to move backward and forward in the scene.
        
        The Display Settings for a 3D Model
        
        From the 3D toolbar (or after right-clicking the 3D model and choosing View Options), choose an option as appropriate to modify the display settings for a 3D model.
        
        Use Orthographic/Perspective Projection Click the Use Orthographic/Perspective Projection icon on the 3D toolbar to toggle between displaying perspective and orthographic projection of the 3D model.
        
        Model Render Modes Click the Model Render Modes icon on the 3D toolbar and choose a desired mode from the drop-down list for the appearance of the 3D shape.
        
        Enable Extra Lighting Click the Enable Extra Lighting icon on the 3D toolbar and choose a desired lighting effect from the drop-down list.
        
        Background Color Click the Background Color icon on the 3D toolbar and choose a desired color from the color picker for the space surrounding the 3D content.
        
        3D Views
        
        In the View pane of the Model Tree panel and in the Views list on the 3D toolbar, you can see a list of available views. Select the desired view to switch among the views. You can also create 3D views with custom display settings and manage existing views.
        
        Display a View
        
        In the View pane of the Model Tree panel:
        
        Select an existing view to display the view.
        
        Click on the Previous View or Next View icon at the top of the View pane to switch to the previous or next view in the views list. (You can also find Previous View or Next View in the Options menu or in the context menu after right-clicking anywhere in the View pane.)
        
        Click on the Default View icon at the top of the View pane to display the default view of the 3D model. The default view lets you quickly revert to the initial or a predefined view that is set as default at any time as you work on 3D content. To change the default view, see also “Manage 3D Views”.
        
        On the 3D toolbar, you can also select a view from the Views list to display it, or click on the Default View icon to switch to the default view of the 3D model. Or, just right-click anywhere anytime in the 3D canvas, choose Views, and select a view to display it.
        
        Create a 3D View with Custom Display Settings
        
        Customize the view as needed. For example, specify the parts to show or hide in the view, and use the tools in the 3D toolbar to set how the parts are displayed.
        
        When you’re done, click the Create View icon in the View pane of the Model Tree panel. (Alternatively, you can click on the Views list in the 3D toolbar and choose Manage Views from the drop-down menu. Then click the New View button in the pop-up Manage Views dialog box to create a view.)
        
        In the pop-up View Properties dialog box, select options for the display settings to include in the new view and click OK. (Note: If you deselect one option, the corresponding setting for it will not be included in the new view. Instead, the previously displayed setting for this option will be used.) Select the Don’t display this dialog from “Create View” button option, so that you won’t be prompted to select options again and the current settings will be used next time you create a view.
        
        The new view will be listed in the Views list in the View pane. To rename it, double-click the name and enter the new name.
        
        Manage 3D Views
        
        With multiple views created, you can use the Manage Views dialog box to perform view management. You can reorder the views in the View pane of the Model Tree panel or in the Views list on the 3D toolbar, delete a view, and set a view as the default view.
        
        Click on the Views list on the 3D toolbar and choose Manage Views to open the Manage Views dialog box. Then do any of the following:
        
        Click New View to create a 3D view. See also “Create a 3D View with Custom Display Settings”.
        
        Select a view and click Move Up or Move Down to adjust the order. The box on the right displays a preview of the order.
        
        Select a view and click Delete View to remove the view from the list.
        
        Select a view and click Use As Default to set the view as the default view of the 3D model.
        
        Select a view, enter the name in the text box, and click Rename to rename the selected view.
        
        Add a 3D Measurement to a 3D Model
        
        With the 3D Measurement Tool, you can measure the distance between two points and the angle between two edges of a 3D model.
        
        On the 3D toolbar (or after right-clicking the 3D model and choosing Tools), select 3D Measurement Tool.
        
        Then the measuring toolbar and the 3D Measurement Tool Info window appear in the upper-right and lower-right corner of the 3D canvas respectively. You can drag them anywhere within the 3D canvas as needed.
        
        Select measurement types, snapping types, and set the scale ratio on the measuring toolbar. The 3D Measurement Tool Info window displays the information about the measurement (such as the current measurement result and scale ratio) and acts as a wizard for your measurement.
        
        Select 3D Point to Point Measurement to measure the distance between two points on the 3D model. Click the first point, move the pointer to the second point, and click. Then the result information (the current measurement result) appears. Move the pointer and click a third time where you want to locate the result information.
        
        Select 3D Perpendicular Dimension to measure the perpendicular distance between two straight edges that are parallel. Click the first point on an edge, move the pointer to the second point on the other edge, and click. Along with the result information, the line leaders on both sides of the measurement points appear as you move the pointer. Move the pointer and click a third time to determine the leader length and set the location of the result information.
        
        Select 3D Radial Dimension to measure the radius of a circular part or a round shape you specified/clicked. With the 3D Snap To Radial Edges option enabled, move your cursor to the edge of a circular part so that a circle appears, and double-click to confirm the measurement. Along with the result information, an arrow appears as you move the pointer and points to the measured circle. Move the pointer and click to set the location of the result information. Without 3D Snap To Radial Edges option enabled, click on three points to specify a round shape you want to measure and then click to specify the location of the result information.
        
        Select 3D Angle Measurement to measure the angle between two edges (or three points). Click three points (A, B, and C) on the 3D model to measure the angle between the line BA and the line BC. Along with the result information, the line leaders on both sides of the first and third measurement points (A and C) appear as you move the pointer. Move the pointer and click a third time to determine the leader length and set the location of the result information.
        
        3D Snap To Edge Endpoints: Snap to the endpoint of an edge when moving the cursor toward the end of the edge.
        
        3D Snap To Linear Edges: Snap to a straight-line segment of an edge when moving the cursor over the edge.
        
        3D Snap To Radial Edges: Snap to the circumference of a circular part when moving the cursor over the circular part.
        
        3D Snap To Silhouettes: Snap to the silhouette for a part (the apparent edge of the part, e.g., the side of a cylinder) when moving the cursor over the part.
        
        3D Snap To Planar Faces: Snap to the geometric plane for a face of a part when moving the cursor over the face.
        
        If the 3D measurement is added to an existing view, the 3D measurement will be listed under that view.
        
        (Optional) Clicking on the result information highlights it, and the icon (four-way arrow) appears. By dragging the icon, you can adjust the location of the result information.
        
        (Optional) To delete a 3D measurement, right-click it in the View pane of the Model Tree and choose Delete.
        
        3D measurements added to a 3D model are associated with the corresponding views. The measurements associated with a view will be invisible once you switch to another view, but will show again when you switch back to the view. However, if you delete a view, the associated 3D measurements will also be removed.
        
        You can press theEsckey to exit the 3D Measurement mode and return to the navigation mode (such as Rotate) at any time as you measure the 3D model.
        
        Comment on a 3D Model
        
        Add a 3D Comment to a 3D Model
        
        You can use the Add 3D Comment tool to add a 3D comment to a particular part of a 3D model, for example, to provide the coordinate information or the name of the part. A 3D comment contains a text box and a connector line that connects the text box and the part of the 3D model you want to comment on.
        
        On the 3D toolbar (or after right-clicking the 3D model and choosing Tools), select Add 3D Comment.
        
        Put the cursor over the desired position you want to comment on and click. Then move the cursor and click again to set the location of the text box.
        
        In the pop-up dialog box, enter a comment string, and click OK to complete or click Cancel to discard the comment.
        In the Default View of the 3D model or with no existing view selected, adding 3D comments creates a new view in the View pane of the Model Tree, with the default name of “CommentView[n]”. You can double-click the view name to rename it. The 3D comment will be listed under the created view (as a child of the view), named “3DComment1”, “3DComment2”, and so on.
        If the 3D comment is added to an existing view, the 3D comment will be listed under that view.
        
        The 3D comment will also be listed in the Comments panel in the navigation pane.
        
        (Optional) After adding the comment, click on the text box, and a handle (a small square icon) appears in the upper-left corner of the text box. Click and drag the handle to resize the box. If the text box is not large enough for the text content, the text exceeding the boundaries of the text box will be invisible.
        
        (Optional) To edit a 3D comment, click the icon beside it in the Comments panel and choose Edit.
        
        (Optional) To delete or reply to a 3D comment, right-click it in the View pane of the Model Tree (or right-click it in the Comments panel), and choose Delete or Reply.
        
        Comments added to a 3D model are associated with the corresponding views. The comments associated with a view will be invisible once you switch to another view, but will show again when you switch back to the view. However, if you delete a view, the associated 3D comments will also be removed.
        
        You can press the Esc key to exit the 3D Comment mode and return to the navigation mode (such as Rotate) at any time as you add a 3D comment to the 3D model.
        
        Add Comments using the Tools in the Comment Tab
        
        You can add comments to a 3D view using the commenting tools in the Comment Ribbon.
        
        Click Comment in the Ribbon, and choose a commenting tool.
        
        Click inside the 3D canvas to create a comment.
        
        In the Default View of the 3D model or with no existing view selected, adding comments creates a new view in the View pane of the Model Tree, with the default name of “CommentView[n]” ([n] is a number that depends on how many existing Comment views are listed in the View pane. For example, if there are two Comment views before the new view is created, n will be 3.). You can double-click the view name to rename it. The comment will be listed under the created view (as a child of the view), named after the comment author. In front of the name shows the icon of the comment type. Clicking the comment in the View pane to view more information on the comment in the Object Data pane.
        
        If the comment is added to an existing view, the comment will be listed under that view.
        
        The comments added from theCommenttab are associated with the corresponding views. They will be invisible once you switch to another view, but will show again when you switch back to the corresponding view.
        
        For comments added using the commenting tools from theCommentRibbon, after their associated views are deleted, you can still find them in theCommentspanel.
        
        The Pencil comments added will not be listed under any view and will be always shown until they are deleted.
        
        Convert 3D Measurements to Comments
        
        You can convert 3D measurements to comments to be reviewed, annotated, and replied to.
        
        In the View pane of the Model Tree panel, expand a view, right-click a 3D measurement you want to convert, and choose Convert to Comment.
        The conversion leaves the name of the original measurement (unchanged) as the name of the converted comment, and the comment is still listed in the same view in the View pane. If you click the comment in the View pane, the Object Data pane will show the author who converted the measurement and the conversion time.
        The converted comment is also displayed in the comments list in the Comments panel in the navigation pane.
        
        (Optional) You can edit, delete, and reply to the comment in the Comments panel by right-clicking the comment and choosing Edit/Delete/Reply. Or delete and reply to the comment directly in the View pane of Model Tree by right-clicking it and choosing Delete/Reply. (Note: A comment converted from a 3D measurement is still associated with the corresponding view. If you delete the view, the comment will also be removed.)
        
        (Optional) You can also move the result information. Please refer to “Add a 3D Measurement to a 3D Model”.
        
        (Optional) To change the comment back to a 3D measurement and remove all the associated comments, right-click it in the View pane and choose Remove Associated Comment, or right-click it in the Comments panel and choose Delete.
