What is a JSF file?

A .JSF file is primarily a web page created using the JavaServer Faces framework. It often contains XML or HTML code. Developers use these files to build user interfaces for Java web applications.

However, .JSF files can have other meanings. Sometimes, a web server generates a dynamic PDF document and gives it the .JSF extension by mistake. Other times, a .JSF file is a Java Script Command File created by Adobe Systems. The extension is also used for sonar and bathymetry data files by Kongsberg Maritime and EdgeTech, single-line font files for JCZ EzCad software, and joystick configuration files for Project64.

How to open JSF files?

Because the .JSF extension has multiple meanings, you must identify the exact format of your file. If it is a web page, you can open it with a text editor like Notepad++ or Visual Studio Code. If it is a downloaded document, you can usually open it with Adobe Acrobat Reader by renaming the file extension to .PDF.

Inspect your file online

If you do not know what type of .JSF file you have, viewer.online/jsf analyzes .JSF files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.

Summary

Because .JSF files use the known XML format, viewer.online/jsf can safely open and display them online, eliminating compatibility problems.
