Open PDFs from Desktop or within Other Applications

By Cynthia, 14 November, 2025

If you set Foxit PDF Editor as your default viewer for PDF files, you are able to launch and open PDF files in the following applications:

  • Email Application: in your email applications, you can double-click the attachment icon to open the document.
  • Web Application: you can open a PDF document by clicking on the PDF file link in your web browser. In a web browser, Foxit PDF Editor will display PDFs in Read Mode by default, hiding the toolbars to maximize the document pane. You can right click the document pane and uncheck Read Mode to show the toolbars and work on PDFs as desired. Also, you can view the PDF content embedded in the HTML. For security purposes, if you try to open an AIP-protected PDF file in your web browser, the file will be opened in the stand-alone Foxit PDF Editor (desktop application) outside the browser. 
  • File System: double-click the PDF file icon in your file system.
