GIF
Graphics Interchange FormatLimited to 256 colours per frame and technically obsolete for a decade, yet immortal because it animates and autoplays everywhere. For anything longer than a few seconds an MP4 or WebP will look better at a tenth of the size.

JXL
JPEG XLThe most technically impressive format of the lot: better compression than AVIF, progressive decoding, and lossless JPEG recompression that shrinks existing photos ~20% with zero quality loss. Browser adoption has been slow and political.

- GIF is lossless, and JXL can be either. At typical quality settings this lands on lossy and trades size for some quality loss. Keep GIF as a source if you may need a higher-detail version later.
Questions about converting GIF to JXL
Is this GIF to JXL converter free?
Yes. Converting GIF to JXL here is free, with no account, no watermark and no daily quota. The work runs on your own device, so there is no server cost to pass on to you.
Is my GIF file uploaded anywhere?
For browser-based pairs, your file is read locally and converted by Squoosh in this tab. No file payload is uploaded; you may still see analytics and engine downloads in network logs.
Is there a file-size limit for GIF to JXL?
There is no imposed upload cap when it runs in-browser, but each conversion still depends on your device and browser memory. Large videos are the first practical limit, then memory-heavy documents or images.
Does converting GIF to JXL lose quality?
It depends on your selected settings and codec path. Many engines can write either lossy or lossless output for JXL, so you can usually increase quality if this file is your final version.
Can I convert several GIF files to JXL at once?
Yes. Drop in several files and each gets its own row; they are processed one after another on your device. You can download them one by one or as one ZIP.
Does GIF to JXL work on a phone, Mac or Chromebook?
Most modern browsers on Windows, macOS, Linux, ChromeOS, Android and iOS work. Very large videos are often more reliable on desktop or a browser with more memory.
Why do some conversions take longer on first run?
The conversion engine has to download first. Small codec bundles are fast, while ffmpeg is commonly 12–30 MB; later conversions of similar type use the cached engine.
I converted a file and the output is blank or unusable. What should I check?
Start over with default settings, then change one option at a time (quality, bitrate, page size, or codec) to isolate what changed behavior. If it keeps failing, retry with a smaller file and confirm the source format matches the pair.
