Frequently asked questions

What is a JPEG XL file?

JPEG XL is a modern image format designed to replace JPG, with better compression, lossless mode, HDR and progressive decoding. JPEG XL compresses better than JPG and can store images losslessly, making it a strong archival and web format where supported.

What can I convert JPEG XL files to?

JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, ICO, PDF. Pick a target after adding your files.

Are my files uploaded to a server?

No. The conversion runs entirely in your browser using WebAssembly. Your files never leave your device, so it is safe for private photos, contracts and business data. Once the page has loaded it even works offline.

Is it free? Are there limits?

It is free, with no sign-up, no watermark and no daily limits. Because nothing is uploaded there is no upload size limit either; the only limit is your device’s memory, which matters mostly for very large videos.
