AVIF vs WebP — Next-Generation Format Showdown
Compare AVIF and WebP, the two leading next-generation image formats. Analyze compression efficiency, browser support, encoding speed, and feature sets to decide which format best serves your needs.
Key Takeaways
- AVIF typically produces files 20% smaller than WebP at equivalent visual quality, and up to 50% smaller than JPEG.
- WebP has ~97% global browser support.
- AVIF encoding is significantly slower than WebP (5-10x), making it less suitable for real-time processing.
- Use WebP as your primary format for broad compatibility.

Compression Efficiency
AVIF typically produces files 20% smaller than WebP at equivalent visual quality, and up to 50% smaller than JPEG. The advantage is most pronounced for photographic content with complex textures.
Browser Support Gap
WebP has ~97% global browser support. AVIF is at ~93%, with Safari support added in version 16.4 (2023). The gap is closing but WebP remains safer for universal deployment.
Encoding Speed
AVIF encoding is significantly slower than WebP (5-10x), making it less suitable for real-time processing. Pre-encode AVIF assets during build time for best results.
Recommendation
Use WebP as your primary format for broad compatibility. Serve AVIF as a progressive enhancement for supported browsers using
