Frequently asked questions
- What makes AVIF better than PNG for the web?

- Does AVIF support transparency?
- Yes - AVIF supports alpha transparency. You can convert logos, icons, and cutout images to AVIF without losing the transparent background.
- How widely supported is AVIF in browsers?
- AVIF is supported in Chrome 85+, Firefox 93+, Safari 16+, and Edge 121+. Roughly 90%+ of global web users are on a supported browser. For the remainder, serve a WebP or PNG fallback using the <picture> element.
