Convert GIF to JPEG XL
Drop a GIF file below and get a JPEG XL back. The conversion happens on your own machine, so nothing is uploaded and there is no size or quantity limit beyond what your browser can hold in memory.

Why convert GIF to JPEG XL?
For the same picture, JPEG XL usually lands well under the size of the GIF original. That matters when you are trimming page weight or squeezing under an upload limit.

Frequently asked questions
Are my GIF files uploaded anywhere?
No. The decoder and encoder are WebAssembly modules that run inside this page. You can verify it by opening your browser’s network tab — converting a file produces no outbound requests. You could even disconnect from the internet after the page loads and it would still work.
Is there a file size or quantity limit?
There is no limit imposed by us. The practical ceiling is your device’s memory, since the image has to be held uncompressed while converting. On a typical laptop, images up to around 100 megapixels convert without trouble.
Will converting to JPEG XL lose quality?
JPEG XL is a lossy format, so some data is discarded. At the default quality setting the difference is not visible at normal viewing sizes. If you need an exact copy of the pixels, choose PNG instead.
Does it work on a phone?
Yes. The same WebAssembly modules run on mobile browsers. Conversion is slower than on a desktop because phone CPUs are weaker, and very large images are more likely to hit memory limits.
What happens to an animated GIF?
Only the first frame is converted. JPEG XL is a still image format, so there is nowhere for the remaining frames to go. If you need to keep the animation, you are looking for a video conversion rather than a still image one.
Is JPEG XL ready to use?
Partly. Safari has supported it for some time and Chrome shipped stable support in early 2026, but overall coverage still sits around 15%. It is a sound choice for archiving, where compression quality matters more than universal support, and a poor one for images going onto a public website today.
