Encode your JPGs to JPEG XL right here in your browser — smaller files at the same visual quality. Great for storage and the Apple ecosystem; note that .jxl won't open in most browsers yet.
.jpg and .jpeg · up to 10 at once · 50 MB each
Four steps, a few seconds, zero uploads.
Drag images onto the box above, or click Browse to pick them from your device.
Pick a JPEG XL quality level — higher keeps more detail, lower makes smaller files. The default suits most photos.
Latch encodes each JPG to JPEG XL, right in your browser — instantly and offline.
Save them one at a time, or grab everything at once in a single zip. That's it.
JPG has been the default photo format for decades, but its compression is dated. JPEG XL is a modern format that stores the same photo smaller at the same visual quality, which makes it appealing for archiving or fitting more into limited storage.
Both formats are lossy, so this tool re-encodes the decoded image. At a sensible quality the result is visually indistinguishable from the JPG while being lighter. Bear in mind you can't recover detail the original JPG already discarded — JPEG XL simply stores what's there more efficiently.
The honest catch is compatibility: as of 2026 only Safari and recent Apple devices open .jxl files — Chrome, Edge, Firefox, and many apps still can't. Keep the original JPG if you need universal reach, convert back any time with JXL to JPG, or use JPG to AVIF for similar savings in a format every current browser supports.
At the same visual quality JPEG XL is typically smaller than JPG, because it uses a far more efficient codec than the decades-old JPEG format. The exact saving depends on the image and the quality setting you pick.
No — this is the main catch. As of 2026 only Safari and recent Apple devices open JPEG XL directly; Chrome, Edge, Firefox, and most apps do not. JPEG XL is best for storage, archiving, or the Apple ecosystem. If you need a file that opens anywhere, keep the original JPG or try JPG to AVIF instead.
This tool re-encodes the decoded image, so like JPG it's lossy. At the default quality the difference is very hard to see, and the file is smaller. Raise the quality slider to preserve more detail. Detail already lost when the original JPG was saved can't be recovered.
Yes. Drop up to 10 JPG files at once and they'll all convert in one go. When done, download them individually or as a single zip file.
No. Every JPG is encoded to JPEG XL by your own browser. Nothing is sent to a server — in fact, the tool keeps working even with your Wi-Fi switched off.
