Open a PDF File

Please choose one of the following to open a PDF file with Foxit PhantomPDF Mac:

Read PDF Files in Multiple Instances

By default, Foxit PhantomPDF Mac displays multiple PDF files in different tabs in a single instance. However, you can enable multiple instances mode to view PDF files in multiple instances when double-click to open PDF files, which is ideal for reading PDF side by side.

To enable multiple instances mode, choose File in the Ribbon (or Foxit PhantomPDF 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.

To change the page display mode, click View in the Ribbon (or choose View in the menu bar > Page Display), and choose any of the following options:

View PDF/A Files

By default, Foxit PhantomPDF Mac will open PDF/A-compliant documents in PDF/A mode (i.e. read-only mode) to prevent modification. When you open a PDF/A-compliant document, a notification message will be displayed. To work with PDF/A files, do the following:

View PDF Portfolios

PDF portfolios are a combination of files with different formats such as Microsoft Office files, text documents and image files.

To view a PDF portfolio, please do the following:

Tip: Files in a PDF portfolio will be opened in its native application if you have installed the native application on your device with macOS 10.14 or higher.

Search & Index in PDFs

Find Text in the Current PDF

Use the Find tool to search and find text.

Advanced Search

Foxit PhantomPDF Mac supports the advanced search function, which enables you to do the following: search a string in a single PDF file, multiple PDF files under a specified folder, PDFs in a PDF portfolio, or a PDF index. When the search finishes, all occurrences will be listed in a tree view. This will allow you to quickly preview the context and jump to specific locations. You can also save the search results as a CSV or PDF file for further reference.

Before doing an advanced search, you can go to File in the Ribbon (or Foxit PhantomPDF in the menu bar) > Preferences > Search to specify search preferences.

Search for Text and Patterns

Tip: The additional search criteria options are collapsed by default. You can click More to show all the options. To keep expanding and displaying the additional search criteria options all the time, please go to File in the Ribbon (or Foxit PhantomPDF in the menu bar) > Preferences > Search, and check the Always show more options in advanced search option in the Search group.


Search and Highlight

After searching, users may need to mark up the searched text strings in a highlight color. With Foxit PhantomPDF Mac’s Search & Highlight feature, users can perform an advanced search and highlight the searched text strings quickly.

Search PDF Indexes

If your PDF document or document collections include a full-text index, you can improve your search efficiency by simply searching the index for target words rather than each document separately. Steps are as follows:

Note: If the index file is not available or does not work, the search will fail. To create or revise an index, please refer to Create PDF Indexes.

Create PDF Indexes

When you are trying to search text in a long PDF document or multiple PDF files, it is much faster to search a PDF index, instead of searching the document(s). With Foxit PhantomPDF Mac, you can create an embedded index for a single PDF, or create a full-text index for multiple PDFs.

Create an Embedded Index in a PDF

For a PDF document that includes an embedded index, you can search the document as you always do through the Advanced Search feature, but it will be much faster than you search a regular PDF without an embedded index. (Note: Before searching a document with an embedded index, you need to select the Enable embedded index option in the File tab(or Foxit PhantomPDF in the menu bar) > Preferences > Index.)

Add an Embedded Index to a PDF

Update or Remove the Embedded Index in a PDF

You can update or remove the embedded index if the document has been changed.

Create a Full-text Index for Multiple PDFs

Foxit PhantomPDF Mac enables you to define a collection of PDFs as a catalog and create a full-text index for the cataloged PDFs, allowing you to search that index through the Advanced Search feature. See also “Search PDF Indexes”.

Create a Full-text Index

Note: The settings above apply to the current index only. To apply these settings to all indexes, please do the settings in the File tab (or Foxit PhantomPDF in the menu bar) > Preferences > Index.

Revise an Existing Index

Take a Snapshot of Selected PDF Contents

Use the Snapshot tool to take a snapshot of selected PDF contents and paste it in other applications.

Check Comparison Results

Once the documents are analyzed, a PDF document named “The result of Comparison.pdf” will be automatically created and opened in a new tab within the application window, and the Compare File panel appears on the right of the document pane. When checking the comparison results, you can click the Compare button  in the View tab to show or hide the Compare File panel.
