FAQ

What happens during PNG to AVIF conversion?

The converter re-encodes the PNG source as AVIF so you can ship a smaller next-generation image when the destination supports it.

Are uploaded files kept permanently?

No. Files are kept only for a short time and downloads are served through temporary links.

Can quality or formatting change?

Yes. Each converter page calls out what is preserved, what may be lost, and which settings matter before upload.
