Got a .jxl file that nothing will open? Convert JPEG XL images to lossless PNG — right here in your browser. Transparency preserved.
Your files never leave this device.jxl · up to 10 at once · 50 MB each
Four steps, about ten seconds, zero uploads.
Drag images onto the box above, or click Browse to pick them from your device.
Latch decodes each JPEG XL image and re-encodes it as a PNG using your browser — instantly and offline.
PNG stores every pixel exactly — no quality compromise. Transparency is preserved if present in the original.
Save them one at a time, or grab everything at once in a single zip. That's it.
JPEG XL (.jxl) is a next-generation image format with excellent compression and quality — but it's so new that almost nothing opens it yet. Outside of Safari, most browsers, photo viewers and editors still can't display a .jxl file, so one you download or are sent can be frustrating to use. Converting to PNG gives you a universally-supported file with no quality loss: every pixel is decoded exactly as stored, with no new compression artefacts.
PNG also supports full transparency (an alpha channel), and so does JPEG XL. If your .jxl image contains transparent areas, only PNG — not JPG — will preserve them faithfully.
The trade-off is file size: a PNG is larger than the original JPEG XL. For images you're publishing online or sharing where size matters, JXL to JPG produces a much more compact result, at the cost of transparency.
JPEG XL is a modern image format designed to replace the original JPEG — smaller files at higher quality, plus lossless compression and transparency. Because it's still very new, most apps and operating systems can't open .jxl files yet, which is why converting to PNG is often the quickest fix.
Yes. JPEG XL supports an alpha channel, and so does PNG. This tool carries transparency through from the JPEG XL source, so any transparent areas in the original are faithfully reproduced in the PNG output.
Yes. The JPEG XL image is decoded exactly, and PNG stores every pixel without compression loss. The PNG will usually be larger than the original .jxl, because JPEG XL compresses far more aggressively — but no quality is lost.
JPEG XL support is still rolling out. Safari opens .jxl files, but most other browsers, image viewers and editors don't yet — so a .jxl you download often won't open. PNG is supported everywhere, which is why converting is the quickest fix.
No. Every .jxl is decoded and converted by your own browser. Nothing is sent to a server — in fact, the tool keeps working even with your Wi-Fi switched off.
Drag your .jxl files onto the drop zone (or click Browse), then hit Convert to PNG. Latch decodes each JPEG XL image and re-encodes it as a PNG right in your browser, then lets you download them one at a time or as a single zip — convert one file or batch several at once.
You can convert up to 10 JPEG XL images at once, each up to 50 MB. Larger batches simply process one after another on your own device — the practical ceiling is your available memory, not a cap on our end.
