Why WebP vs AVIF?
WebP and AVIF are both modern image formats designed to replace JPEG and PNG on the web. But which one should you use?
WebP (Google, 2010): Mature format with 97%+ browser support. Offers 25-35% smaller files than JPEG. Fast encoding, widely supported by CMSs and CDNs.
AVIF (AOMedia, 2019): Newer format with 93%+ browser support. Offers 50%+ smaller files than JPEG. Slower encoding but better compression, especially at low bitrates.
The verdict: Use AVIF for best compression with a WebP fallback for older browsers. Or use WebP alone for simplicity and near-universal support.

Yes! Use the HTML <picture> element to serve AVIF to browsers that support it, WebP to others. This gives you best compression with full compatibility.
At the same file size, AVIF generally looks better, especially at high compression. At typical web quality (80%), both look excellent.
Safari supports both WebP (since Safari 14) and AVIF (since Safari 16). Modern Safari handles both formats well.
