macOS added JPEG XL support relatively recently, but if your Mac or a specific app still refuses to open a .jxl, you do not have to fight with it. Drop the file here and it is decoded in your browser and shown instantly, with nothing uploaded. You can then export a PNG or JPG that opens in any Mac app, including older ones. It is the fastest way to view a JPEG XL image without changing system settings or installing software.
How it works
- 1Choose or drop your .jxl file(s).
- 2The image is decoded and shown instantly — right in your browser.
- 3Download it as PNG, JPG, or WebP. Nothing is uploaded.
FAQ
Can macOS Preview open JXL?
Recent macOS versions (Safari 17 era and later) can render JPEG XL, so Preview and Quick Look may work. If yours does not, the in-browser viewer here always works.
Will this work in Safari?
Yes. The viewer runs in any modern browser on macOS, including Safari and Chrome.
Are my files uploaded?
No. Decoding happens locally in your browser; files never leave your Mac.
