Optimize JPEG XL images in a browser-only batch. Every successful result remains JPEG XL, and files are never uploaded.
Every successful output remains JPEG XL.
Files stay in this browser tab and are never uploaded. Up to 50.0 MiB per file and 200 files.
The batch workspace is ready. Compression becomes available when the verified image optimization adapter loads.
The browser decodes, optimizes, and re-encodes each file as JPEG XL. The tool never switches formats automatically.
JPEG XL compression supports high-quality lossy or lossless settings while retaining compatible alpha, wide-color information, and selected metadata.
