In-browser JPEG XL converter keeps images private, no upload needed
A developer built a tool that converts images to and from JPEG XL entirely in the browser using WebAssembly, with no server upload. It supports JPG, PNG, WebP, GIF, and HEIC, and uses the libjxl library compiled to WASM. The tool addresses the lack of native browser support for JPEG XL while preserving user privacy.
