Frequently asked questions

Are my PNG images stored?

No. Files are held in memory only for the conversion request and are not written to permanent storage.

What quality should I use for AVIF?

Quality 50 is a balanced AVIF starting point. AVIF can remain visually strong at lower numerical quality than older formats.

Can I convert several images together?

Yes. Add up to 10 images, convert the queue, and download results individually or in one ZIP file.
