Frequently asked questions
Does AVIF keep my PNG transparency?
Yes, AVIF has full alpha support: transparent logos and icons are preserved.
Do I lose quality?
AVIF is lossy (at your chosen quality). For flat graphics the result is visually identical at a fraction of the size.
Which browsers can encode AVIF?
Recent Chrome, Edge and Firefox. If yours cannot, the tool detects it and tells you before you start.
Will older browsers display my AVIFs?
Modern browsers (since ~2021) do. For maximum compatibility serve AVIF with a WebP/JPG fallback using <picture>.
