WebP vs AVIF — which should I use?

AVIF typically produces files 20-50% smaller than WebP at the same visual quality. It supports HDR and wider color gamuts. Tradeoffs: encoding is slower, and Safari's encode support is limited.

WebP has near-universal browser support and faster encoding. For photos, AVIF wins on size. For the broadest compatibility today, WebP is still the safer choice.

Frequently asked questions

Does my browser support AVIF encoding?

Chrome 85+, Firefox 113+, and Edge 121+ support AVIF encoding via canvas. Safari supports decoding but encoding is limited. PixlFits detects support and falls back automatically.

Why is AVIF encoding slow?

AVIF uses a more sophisticated compression algorithm. A typical 4K photo encodes in 3-15 seconds depending on your CPU. Lower quality settings are faster.

Can I batch convert?

This tool is single-image. For batch WebP ↔ JPG ↔ PNG conversion with ZIP download, use PixlFits Image Converter.
