Frequently asked questions

Yes. AVIF supports full alpha transparency, so PNGs with transparent or semi-transparent regions convert cleanly without losing the alpha channel.
This tool converts to lossy AVIF (which is what makes it dramatically smaller than PNG). The quality is visually indistinguishable for photos and most graphics.
