CKEditor is a browser-based HTML text editor with a WYSIWYG interface. It is not an application you install on a computer. It’s an application you integrate to websites. The correct question is: “Which browsers are compatible with CKEditor?”

All popular browsers are supported, including Chrome, Firefox, Internet Explorer, Opera and Safari. Please note that as of CKEditor 4.0 Internet Explorer 6.0 will not be supported. CKEditor 4.1.3 is the last version to support Internet Explorer 7 and Firefox 3.6.

The latest version of Safari is actively supported. Earlier versions may have compatibility issues.

CKEditor supports mobile versions of Safari (default browser on iPhone and iPad) and Chrome (available for Android and preinstalled on many Android devices) with minor issues related to platform limitations.

Full mobile support will be introduced in CKEditor 5. We aim to have perfect CKEditor support for most popular mobile platforms, so if you encountered an issue on not yet supported environment please report it on our development site.
