FlexiPDF NX and 2025

List of changes

2025-10-07: Revision 414

  • The 64-bit version of FlexiPDF is now ready for productive use! After a successful preview phase, service pack 414 brings you the stable 64-bit version of FlexiPDF. It is able to utilize the entire memory of your system, enabling you to open even extremely large PDF files effortlessly.

    Note: If you are using 64-bit Windows, we recommend the 64-bit version of FlexiPDF. The only exception is TWAIN scanning. Although the 64-bit version of FlexiPDF supports TWAIN, 64-bit TWAIN drivers are practically nowhere to be found. For TWAIN scans, stay with the 32-bit version. For WIA scans, you can use the 64-bit version without hesitation.

    We recommend that you do not install the 32-bit and 64-bit versions in parallel.

  • Opening PDFs by double-clicking works again even when FlexiPDF is already running.

2025-08-12: Revision 412

  • New feature: You can choose in File | Options whether documents open in new tabs, new windows or in the same window.
  • PDFs with a master password can now be opened for editing.
  • 64-bit version: We are pleased to announce the second preview of the 64-bit version. Thanks to the users’ feedback, we were able to correct some problems that only occurred with the 64-bit version.

2025-07-22: Revision 410

  • New feature: If you open a PDF in Windows Explorer and FlexiPDF is already running, the PDF file no longer appears in a new instance of FlexiPDF, but as another document tab in the running program.
