    Why convert to JXL?

    JXL is the format to pick when a file has to work somewhere else: an upload form that takes one format only, a colleague on different software, a phone that shows a blank thumbnail instead of a photo. Converti reads JPG, PNG, WebP and every other format it accepts, writes JXL at the highest quality the format allows, and the result is ready to download a few seconds later.

    How to convert an image to JXL

    1. Click "Choose images" or drag your files into the upload area.
    2. Check that the output format is set to JXL, and adjust the quality if you need to.
    3. Press "Convert" and download your JXL files. Several files arrive as a ZIP.
