Frequently Asked Questions
For most websites, WebP offers the best balance of compression and browser support. If you need maximum compression and target modern browsers exclusively, AVIF with WebP fallback is ideal. Use the HTML <picture> element to serve AVIF to supported browsers and WebP as a fallback.
AVIF is supported by Chrome 85+, Firefox 93+, and Safari 16+ — covering approximately 85% of web users as of 2025. Internet Explorer does not support AVIF. Always provide a WebP or JPEG fallback.
At very low file sizes (high compression), AVIF maintains significantly better quality than WebP. At moderate compression levels for typical web images, the difference is less noticeable. AVIF particularly excels for high-contrast and photographic content.
