Why choose AVIF over JPG?

AVIF achieves the same perceived quality as JPG at a much smaller size, and handles gradients and flat colour with less banding. The trade-off is slightly slower encoding and less support in older tools.

Is the conversion lossy?

At the default setting yes, like JPG. Raise the quality slider to keep more detail, or lower it to shrink the file further.

Are my files uploaded to a server?

No. The whole conversion runs in your browser using your device's own processor. Your files are never sent anywhere.
