Convert WebP to AVIF Free

AVIF is the next step up from WebP, offering 20-30% better compression at equivalent quality. If you are already using WebP, converting to AVIF yields additional file size savings - particularly valuable for high-traffic websites where every kilobyte counts. AVIF also supports HDR and wide-colour-gamut images, which WebP does not. A practical strategy: serve AVIF to supported browsers and WebP as a fallback.

Frequently asked questions

Is AVIF meaningfully better than WebP?
In most cases yes - AVIF typically achieves 20-30% smaller files than WebP at equivalent visual quality, and handles gradients and complex textures better. The trade-off is slower encoding time.
Can I use AVIF with a WebP fallback?
Yes - this is the recommended approach. Use the HTML <picture> element: offer AVIF first, WebP second, then JPG for maximum compatibility. Most modern web frameworks and CDNs can automate this.
Does AVIF support transparency like WebP?
Yes - AVIF supports full alpha transparency. Converting a WebP with transparent areas to AVIF preserves the transparency completely.
