• (Only available in the edition downloaded from Foxit official website) Click the Start tab, and click any file in the Recent Files list (if any) to open a recently opened file, or click Open File to open a file from your local device.

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.

View PDF Properties

To view the PDF properties, please navigate to File > Properties. You can acquire all relevant information as follows:

• Description: This tab shows some basic information about the document. The person who created the document in the source application may have set the title, subject, author, and keywords. Click Custom, and the pop-up Custom Properties dialog box shows some document information (such as comments and the company name).
• Security: This tab describes security permissions and what functionality is allowed within a PDF.
• Fonts: This tab lists the fonts and the font types used in the original document, as well as the encoding used to display the original fonts.

Render Text, Line Art, and Thin Lines

While rendering PDF files, Foxit PDF Reader automatically smooths the jagged edges of text and line art (including path and shading objects) and enhances thin lines to improve their appearance and readability. To change the default settings, please go to File in the Ribbon (or Foxit PDF Reader in the menu bar) > Preferences > Page Display, and modify the following options in the Rendering group.

To enable multiple instances mode, choose File in the Ribbon (or Foxit PDF Reader in the menu bar) > Preferences > Documents, check the Allow multiple instances option in Open Setting group, and click OK to apply the setting. While in multiple instances mode, you can revert to single instance mode by redoing the steps and unchecking the Allow multiple instances option.  

Adjust PDF Views

Change the Page Display Mode

For a PDF file that does not include the preset page layout, Foxit PDF Reader will open it with the default page display mode or the last viewing settings (if you have enabled the application to restore the last view settings when reopening PDF files in Preferences > History). To change the default page display mode, please go to the File tab (or Foxit PDF Reader in the menu bar) > Preferences > Page Display > Default Layout and Zoom, and select the desired option from the Page layout drop-down list. To change the page display mode while reading PDF files, click View in the Ribbon (or choose View in the menu bar > Page Display), and choose any of the following options:

    • To specify the frequency to automatically advance from page to page in Full Screen mode, please check the Advance every _ seconds option, and input a number (any integer between 1 and 99999). With this setting enabled, you can still page through a document manually using your mouse or keyboard shortcuts.
  • In the Full Screen Appearance group, click the color palette to choose the background color in Full Screen mode.
  • In the Full Screen Transitions group, choose a default transition and its direction from the drop-down list. If you need to control the page transition based on your navigation direction, check the Navigation control direction option. To ignore all transitions, check the Ignore all transitions option. Please note that the default transition settings in Preferences are specific to the application. The page transitions specified in a PDF document (if any) will prevail over the default settings.

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.
  • Minimum number of pages in a large document: When the “For large documents, only read the currently visible pages” option is selected, it allows you to set this minimum value.
  • Enable assistive technology support: Check this option to allow assistive technology products, such as screen readers, to provide information about the UI and document to end users.
  • Confirm before preparing untagged PDF for reading with assistive technology: Select the option, and if any assistive technology is detected in your system, a dialog box pops up when you open an untagged PDF to ask you whether to set the reading order options for the PDF for reading with assistive technology.  
• Reading Order Options
  • 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.
  • Override the reading order in tagged documents: Use the reading order specified in the Reading preferences instead of what the tag structure of the document specifies. Use this preference only when you encounter problems in poorly tagged PDFs.

Work on 3D Content in PDFs

Set 3D Preferences

Foxit PDF Reader lets you view and navigate 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 set different visual effects, rotate/spin/pan/zoom a 3D model, create and manage 3D views with different settings, 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 turn a 3D model around to view it from all orientations.

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.

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.
• 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.
