About JXL to JPG

Convert JPEG XL (JXL) images into JPG that works everywhere. JXL is a powerful next-gen format but still thinly supported, so we decode it and re-encode it as a JPG at the quality you choose for a file every app and browser accepts.

Decoding and encoding both happen in your browser via WebAssembly. The JXL file you drop in never leaves your device, so the conversion is completely private.
