WebP to AVIF Converter
Already shipped your images as WebP? AVIF's encoder usually finds another 20–30% of savings at the same visual quality — meaningful at scale for image-heavy pages. Re-encode locally in your browser: drop the WebP, compare the live size readout, download the AVIF.
For a handful of images, the savings are modest. Across a whole site — hero images, illustrations, screenshots — 20–30% less on the largest assets shows up directly in load times and bandwidth. CDN image services made exactly this migration their default.
The live before/after readout settles it per image: if AVIF comes out bigger or barely smaller, keep the WebP.
The alpha channel survives the trip, so transparent logos and graphics stay transparent. Encoding runs a few seconds per image — AVIF's analysis is heavier than WebP's, and those seconds are what buy the smaller files.
Typically 20–30% at the same visual quality, with photographic and gradient-heavy images saving the most. Flat, tiny graphics may see little benefit — check the live readout per image.
Both formats are lossy, so a second lossy encode compounds slightly — at quality 90 the difference is visually undetectable. Keep your original source files as the master copy.
Yes — that's the standard modern pattern: a <picture> element with AVIF first and the WebP as fallback for browsers without AVIF support. The WebP you already have is that fallback.
Chrome, Edge, Firefox and Opera have for years; Safari since 16.4 (2023). Combined coverage is comparable to where WebP stood a couple of years into its rollout.
