The converter runs locally via WebAssembly, is free, requires no sign-up, imposes no limits and adds no watermark.
It supports bidirectional conversion between JPEG XL and common formats such as JPG, PNG, WebP, HEIC and GIF.
A built-in viewer lets users open .jxl files, and the tool notes that Safari already supports JPEG XL while Chrome’s decoder is off by default until Chrome 145 re-enabled it in 2026.
