WebP to AVIF Features
• Modern compression algorithm for better efficiency
• Preserves PNG transparency
• Small file size saves storage space
• Perfect for website optimization
WebP was Google's answer to bloated JPGs and PNGs, but AVIF pushes compression further still — typically 20–30% smaller than an equivalent WebP at the same visual quality. Image Machine handles the re-encoding entirely in your browser using the AV1 codec, giving you today's most efficient raster format without any file ever touching a server.

Frequently Asked Questions
Is AVIF actually better than WebP for compression?
In most independent benchmarks, AVIF produces smaller files than WebP at the same visual quality — typically 15–30% smaller. The gap is most noticeable at low to medium quality settings, where AVIF's AV1 codec retains more detail with fewer artifacts than WebP's VP8/VP9 encoder.
Which browsers support AVIF versus WebP?
WebP enjoys near-universal browser support today. AVIF has slightly narrower coverage: Chrome 85+, Firefox 93+, Edge 121+, and Safari 16.4+. Neither works in Internet Explorer. If you are targeting only modern browsers, AVIF is a straightforward and worthwhile upgrade over WebP.
Does converting WebP to AVIF preserve transparency?
Yes — both formats support alpha transparency, so the conversion is clean. Transparent areas in your WebP file map directly to equivalent transparent areas in the AVIF output. No background color is imposed, and the alpha channel carries over faithfully.
Does AVIF support animation like WebP?
Yes, AVIF supports animation via the AVIF image sequence format. However, animated AVIF has less tooling and browser support than animated WebP today. For still images, AVIF is clearly the better choice; for animations, animated WebP remains the more practical option.
Will switching my site's WebP images to AVIF improve page speed?
In most cases, yes. Smaller image files directly reduce load time for image resources and can improve Core Web Vitals scores like Largest Contentful Paint. Even a 20% reduction in image weight is meaningful on image-heavy pages, and AVIF typically delivers more than that.
