IrfanView JPEG XL support

What is IrfanView?

IrfanView is a free program for Windows that allows the user to view, edit, organize, and convert images. It is a small, fast, and easy-to-use program that can handle a wide variety of graphic formats. Furthermore, it is capable of creating and painting pictures as well as playing video and audio files. A free version of IrfanView is available for non-commercial use, whereas a registered version is available for commercial use. It was first released in 1996.

IrfanView JXL Support

A new evaluation copy of IrfanView has recently been released by the developer, which includes JXL support. A Reddit user, Jaystarx, has been in touch with the developer and provided a link to the version on the JPEG XL subreddit. Upon consultation with the developer, he made the version available for experienced JXL users to test Irfanview's compatibility to ensure that it works correctly before the official release.

Irfanview can also be associated with JXL files if you want to click on the JXL file directly from Explorer. Go to the menu: Options > Properties/Settings > Extensions, and in the list of file-types, tick the 'JXL' checkbox.
Please note: The JXL library is still in active development. With new APIs being added, certain features being rewritten, and possible bugs and security issues have yet to be tested.
