Frequently Asked Questions
- Why is this tool server-only?
- JPEG-XL encoding via libjxl is not available in browser WebAssembly. Server-side FFmpeg 8.0 includes full libjxl support for animated JXL encoding.
- Which browsers support JPEG-XL?
- Safari 17+ and Firefox 135+ support JPEG-XL natively. Chrome removed JXL support. For other browsers, you can use a JXL viewer or convert back to GIF/WebP.
- How does animated JXL compare to GIF?
- Animated JXL offers dramatically better compression than GIF — typically 50-80% smaller files — with full color depth (vs GIF's 256 colors), alpha transparency, and no banding artifacts.
- What does the effort setting do?
- Effort controls the trade-off between encoding speed and file size. Effort 1 is fastest but produces larger files. Effort 9 produces the smallest files but takes longer to encode.
