What is JPEG XL?
JPEG XL (JXL) is a next-generation image format offering superior compression and quality. Firefox 152 adds native support in June 2026, and Chrome has experimental support behind a flag. Use this converter to open JXL files or create them from your existing images.
How it works
- All conversion happens in your browser using WebAssembly — no files are uploaded to any server.
- Supports batch conversion — drop multiple files at once.
- JXL decoding and encoding powered by the libjxl reference implementation.
