What is a PFF file?
A .PFF file is a file format that serves several different functions depending on the software that created it. The most common use is a fillable electronic form. This includes the Printable Form File used by Adobe Acrobat Pro and the Formatta Portable Form File developed by Phreesia.
Other software also uses the .PFF extension. The CSPro data entry application from the U.S. Census Bureau uses .PFF for project configuration files stored in UTF-8 text. Additionally, some .PFF files are game resource archives used in games from Volition Inc. or *Star Trek: Armada*, parametric CAD plot files created by PTC Creo, or lighting fixture definitions for Freestyler DMX.
How to open PFF files?
Because .PFF files have multiple possible formats, opening them requires the specific software that created them. If it is a Formatta Portable Form File, you need a dedicated form viewer. If it is a CSPro project, you must use the CSPro desktop application. Game archives often require community-made extraction tools to view the internal files.
Analyze with viewer.online
Because a .PFF file has multiple possible meanings, viewer.online/pff can analyze .PFF files to identify the exact format and creator software. You can inspect the file structure, extract readable text, and check whether an online preview is available.
Summary
viewer.online/pff is useful for identifying, inspecting, and understanding .PFF files without installing software or dealing with compatibility problems.
