System Requirements

This website contains links to software which is either no longer maintained or will be supported only until the end of 2019 (CKFinder 2). For the latest documentation about current CKSource projects, including software like CKEditor 4/CKEditor 5, CKFinder 3, Cloud Services, Letters, Accessibility Checker, please visit the new documentation website.

If you look for an information about very old versions of CKEditor, FCKeditor and CKFinder check also the CKEditor forum, which was closed in 2015. If not, please head to StackOverflow for support.

Browsers

Currently, any of the following browsers is required for CKFinder to run:

  • Google Chrome
  • Firefox
  • Internet Explorer 8+
  • Safari
  • Opera
important note

Some features depend on your browser settings. CKFinder should work in any of the browsers listed above with their default settings enabled. If you are experiencing problems with the Context Menu or your Settings are not being saved, make sure that your browser is configured to "allow scripts to replace context menus" ("allow scripts to receive right clicks") and that you have "cookies support enabled".

Please contact your system administrator if you have any doubts.


Server

Minimum CKFinder requirements for Java:

  • JRE 1.6 and a Servlet 2.5/JSP 2.1 compliant server.
important note
The requirement of JDK or JRE is dependent on the particular application server itself. Some servers like Apache Tomcat require JRE and others like GlassFish or JBOSS require JDK. While JRE is the minimum requirement that will work with some servers, JDK is the recommended requirement which will work with all the servers.
