Convert to

JPEG XL

JPEG XL is a newer format from the JPEG committee. iPhones from iOS 17 can save ProRAW photos in it.

Safari opens JPEG XL natively; elsewhere Nibbo decodes it on your device with a small WebAssembly decoder, so you can also convert JPG or PNG into it.

PNG

PNG is lossless and supports transparency, so it is used for screenshots, logos and graphics with sharp edges.

For photos PNG files are several times larger than JPG, which matters when a form or a message has a size limit.

How it works

  1. Your JPEG XL files are decoded by the browser on this device and saved as PNG. Photos keep their orientation.
  2. Drop many files at once and download them one by one or as a ZIP.
  3. Metadata such as GPS location is removed by default; switch it off to keep EXIF in JPG files.

Questions

Which browsers can open JPEG XL?

Safari 17 and newer decode JPEG XL natively. Other browsers don’t yet, and the page tells you if yours can’t.

Are my files uploaded?

No. Conversion happens in your browser; nothing is sent to a server.

Which licence do the codecs use?

The AVIF and WebP encoders are Apache-2.0 builds of libavif and libwebp. The HEIC decoder is libheif (LGPL-3.0), loaded as a separate file rather than built into our code.
