Upgrade Animated GIFs to JPEG XL
The 1989 GIF format is limited to 256 colors per frame and LZW compression, making short animations several megabytes in size. Converting GIF to JPEG XL uses modern inter-frame patch references and ANS coding to cut file sizes by 50–85%.
100% Local Privacy
Powered by WebAssembly (`libjxl`). Your images are processed inside your browser tab and never uploaded to any cloud server.
Reversible JPEG Recompression
Losslessly transcode existing `.jpg` files into `.jxl` (~20% smaller) and reconstruct the exact bit-for-bit `.jpg` whenever needed.
Batch & ZIP Archive Workflow
Drop dozens of images or a `.zip` archive at once. Download converted files individually or bundled in a single `.zip`.

Frequently Asked Questions
Are all animation frames and frame delays kept?
Yes. libjxl reads the GIF animation stream directly and encodes every frame along with its exact frame delay and loop count into the output .jxl file.
Can I convert animated JXL back to GIF later?
Absolutely. Use our JXL to GIF converter at any time to turn animated .jxl files back into standard .gif animations.
