Image format has a big impact on how fast your site loads — and speed affects both visitors and Google rankings. Here is the simple, modern answer.
The quick recommendation
- Photos: use AVIF (smallest) or WebP (great support). Fall back to JPG for old browsers.
- Logos, icons, screenshots: PNG or WebP (both support transparency).
- Animations: animated WebP — far smaller than GIF, same quality.
Why modern formats matter
WebP and AVIF can be 50–90% smaller than the equivalent JPG, PNG or GIF. Smaller images mean faster pages, lower bounce rates and better Core Web Vitals.
