JXL to JPG Converter

Turn JPEG XL images into JPGs that every app, phone and upload form accepts - decoded right in your browser. Need transparency kept? Use JXL to PNG.

How to convert JXL to JPG

  1. Add your JXL files. Drop up to 50 JPEG XL files into the box, or browse for them. They are decoded in your browser - nothing is uploaded.
  2. Set the JPG quality. Quality 90 looks like the original. Transparent areas get a background colour - white by default.
  3. Adjust if you like. Resize, change the background or rename the files. Every option starts closed and shows its value.
  4. Convert and download. Press Convert to JPG. One or two files download directly, more than two come as a ZIP.

Tips

  • Quality 85-90 keeps photos looking the same.
  • Upload limit? Open Max file size and pick 200 KB or 500 KB.
  • Chrome, Edge and Firefox cannot open JPEG XL themselves - this page brings its own decoder (libjxl), so it works in every modern browser. Safari 17+ uses its built-in one.
