About this conversion
JPEG XL offers excellent quality at small file sizes and can re-encode existing JPEGs without any further quality change, but lacks widespread browser support.
Common questions
Are my files uploaded to a server?
No. The conversion runs entirely in your browser. Your files never leave your device.
Will converting to JPEG XL reduce quality?
JPEG XL uses light compression that makes a small change to pixel values. At the default quality setting the difference is usually invisible, but it is not pixel-for-pixel identical to the original. You can raise the quality slider to reduce the change, at the cost of a larger file.
