WebP vs AVIF — which should you use?
WebP
The reliable all-rounder — widely supported and much smaller than JPEG. Best when compatibility and encoding speed matter.
AVIF
Offers even better compression, especially for photos. Ideal when maximum performance and smallest file sizes are the priority.
Simple recommendation
- ▸Choose AVIF when you want the smallest possible files (especially for photographs) and can provide a fallback.
- ▸Choose WebP when encoding speed or maximum browser compatibility is more important.
- ▸Best approach for websites: serve AVIF first, then WebP as fallback, with JPEG as the final fallback.
Free WebP converter — no uploads, no limits
This is a completely free online WebP converter that runs 100% in your browser.

Using WebP on your website reduces file size by 25-35% compared to JPEG and PNG, which improves Core Web Vitals scores and helps your pages rank higher in Google search results.
