About this conversion
AVIF delivers the smallest file sizes of any mainstream image format and works in Chrome, Firefox, and Safari — though encoding is slower than older formats.
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 AVIF reduce quality?
AVIF 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.
