Convert JPG to JPEG XL and Shrink Your Photo Library
JPEG XL is the successor JPEG was waiting for: the same photos at a fraction of the size, now viewable in Chrome, Firefox and Safari. This free JPG to JXL converter re-encodes your .jpg and .jpeg images to .jxl entirely in your browser — no uploads, no queues.
Smaller Files, Same Look
JPEG XL's modern compression typically produces noticeably smaller files than JPEG at the same visual quality — ideal for photo libraries and fast websites.
Batch Convert + ZIP Download
Drop in a whole album, convert it in one run, then download each JXL or grab them all in a single ZIP archive.
Private by Design — Nothing Is Uploaded
Most online converters send your photos to a server. This tool encodes entirely on your device with WebAssembly, so personal photos stay personal.
