About JXL Viewer

JXL Viewer exists to solve one annoying problem: you get a .jxl file and nothing on your computer will open it. JPEG XL is a modern, efficient image format, but most browsers and apps still do not support it by default.

Instead of installing software or uploading private photos to a stranger’s server, you can drop the file here and see it instantly — everything runs locally in your browser. If you need a copy that works everywhere, export it to PNG, JPG, or WebP in one click.

No accounts, no watermarks, no uploads. Just a fast, focused tool.
