AVIF vs WebP — choosing the right format

AVIF achieves the best compression of any common image format — typically 50% smaller than WebP and 70% smaller than JPEG at the same visual quality. However, AVIF browser support (~90%) and tool support lag behind WebP (~97% browser support, widely supported in design tools).

Converting AVIF to WebP gives you a format that is nearly as efficient as AVIF with substantially broader compatibility — supported by more browsers, CDNs, CMS platforms, and image processing tools that don't yet handle AVIF.

When to convert AVIF to WebP

  • When your image pipeline or CMS doesn't support AVIF yet
  • When targeting browsers that support WebP but not AVIF (older Edge, some mobile)
  • When using tools like Figma or Sketch that don't import AVIF
  • WebP is a safe "almost as good" fallback when AVIF causes compatibility issues

Frequently Asked Questions

Is WebP or AVIF the better format?
AVIF achieves better compression — typically 20–50% smaller than WebP at the same quality. But WebP has broader compatibility (97% vs ~90% browser support) and better tool support. For cutting-edge sites: AVIF. For broad compatibility with still-excellent compression: WebP.
Will the WebP be larger than the AVIF?
Yes. AVIF has superior compression. Converting AVIF to WebP produces a larger file. If you need the absolute smallest file size, keep the AVIF where it's supported.
Does AVIF to WebP preserve transparency?
Yes. Both AVIF and WebP support full alpha-channel transparency. Converting AVIF to WebP preserves all transparent areas.
What is the practical difference between 90% and 97% browser support?
The gap is mostly older browsers: Safari before version 16 (2022) lacks AVIF support. For most modern sites, both formats work fine. If your analytics show significant traffic from older iOS devices (iPhone running iOS 15 or earlier), WebP is the safer choice.
Can I convert multiple files at once?
Yes. Drop as many files as you need in one go and click "Convert all" to process everything at once. When done, click "Download all" to get a single ZIP archive containing all converted files.
Are my files uploaded to a server?
No. All conversion happens directly in your browser using the Canvas API. Your files never leave your device — no uploads, no server processing, 100% private. This also means the tool works without an internet connection once the page has loaded.
