AVIF vs WebP
Weigh the trade‑offs between AVIF and WebP for your site. Both deliver excellent compression; your audience and content determine which wins.
AVIF offers superior compression for photographs, sometimes beating WebP at equivalent visual quality. However, encoding can be slower and older browsers may need fallbacks. WebP is broadly supported and delivers strong results for both photos and graphics.
Consider transparency and animation needs. Both formats support transparency, but implementation quirks vary across tooling. If you rely on animated content, validate support and size implications against GIF and video alternatives.
Migration strategy matters. Start with high‑traffic pages, convert hero images, and measure impact. Provide fallbacks for non‑supporting browsers with `picture` and source elements. Avoid reconverting already compressed assets repeatedly to prevent quality loss.
In practice, a hybrid approach is common: use AVIF for heavy photos, WebP for UI graphics, and JPEG/PNG as fallbacks. Test on real devices and monitor telemetry, then adjust the mix based on audience capabilities.
