FAQ

What happens during JPG to AVIF conversion?

The converter decodes the JPG source and re-encodes it as AVIF for smaller next-generation image delivery.

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.
