What is JPEG XL?

JPEG XL (.jxl) is the modern successor to the classic JPEG. It produces noticeably smaller files at the same — or better — quality than JPEG, PNG and WebP, and it can shrink existing JPEGs by about 20% with no quality loss at all.

📦

Smaller files

Keep the same visual quality while cutting file size, so pages load faster and storage goes further.

🎞️

One format, everything

Lossless and lossy, photos and graphics, transparency and animation — all in a single modern format.

🔁

Lossless from JPEG

Re-pack your existing JPEGs to JPEG XL and recover ~20% of their size without touching quality.

Frequently asked questions

Is it really free?

Yes — completely free, with no sign-up, no daily limits and no watermark.

Are my images uploaded anywhere?

No. Every conversion runs locally in your browser using WebAssembly. Your files never leave your device, so it's safe even for private documents and photos.

Can I convert a .jxl back to JPG or PNG?

Yes. The tool works both ways: turn images into JPEG XL, or open a .jxl file and convert it back to PNG or JPG.

Why can't my browser open .jxl files yet?

Most browsers are only now re-adding native JPEG XL support (Chrome is rolling it out). Until then, converting .jxl back to PNG/JPG here lets you view and share them anywhere.

Does it work on my phone?

Yes. It runs in any modern browser on desktop, Android and iOS.
