JPEG XL (.jxl) is a next-generation format that compresses images smaller than JPEG while keeping more detail. The problem is support: outside of Safari, most browsers, photo viewers and editors still can't open a .jxl file, so one you download or are sent may simply refuse to open. JPG, by contrast, opens in virtually every app on every platform.
Converting to JPG trades a little file size for universal compatibility. If you instead need to keep transparency or want a lossless copy for editing, JXL to PNG is the better choice.
JPEG XL is a modern image format meant to succeed the original JPEG — smaller files at higher quality. It's still very new, so many apps and operating systems can't open .jxl files yet, which is why you might end up with one you can't view. Converting to JPG gives you a file that opens almost anywhere.
JPEG XL support is still limited. Safari can display .jxl files, but most other browsers, image viewers and editors don't support them yet. Converting to JPG gives you a universally-compatible file that opens on any device.
No. The JPEG XL is decoded and re-encoded entirely in your browser. Nothing is sent to a server — the tool works offline too.
92% quality is a great default — visually almost identical to the original with a manageable file size. JPG has no transparency, so any transparent areas in the .jxl are filled with the background colour you choose (white by default). Pick a colour that suits where you'll use the image.
Yes. Drop up to 10 JXL files at once and they'll all convert in one go. When done, download them individually or as a single zip file.
