Convert WebP to AVIF
Convert WebP to AVIF for a further ~ 20% file-size reduction. AVIF wins on file size; WebP wins on compatibility. This preserves both.
AVIF typically produces files ~ 20% smaller than WebP at equivalent visual quality. For sites where every KB matters, converting existing WebP libraries to AVIF (while keeping WebP as a fallback) gives you the smallest-possible files on modern browsers.
AVIF encoding is 5–10× slower than WebP. For a one-time asset conversion that's fine; for dynamic pipelines think carefully.

Frequently asked questions
- How do I convert WebP to AVIF?
- Drop your WebP file into the tool above. It's converted to AVIF in the browser and ready to download. Multiple files can be converted at once.
- Why convert WebP to AVIF?
- AVIF typically produces files ~ 20% smaller than WebP at equivalent visual quality. For sites where every KB matters, converting existing WebP libraries to AVIF (while keeping WebP as a fallback) gives you the smallest-possible files on modern browsers.
- Is any quality lost when converting to AVIF?
- Converting between lossy formats (like JPG to WebP) involves one round of re-encoding, so there is theoretically some quality loss — but at the default quality setting it's visually indistinguishable. Converting to a lossless format (PNG) doesn't lose data from the source.
- Does the AVIF file work everywhere the WebP did?
- Modern browsers, image editors, and platforms all support AVIF. Older tools (2015-era software, some third-party services) may not — if you need maximum compatibility, JPEG or PNG remain the safest fallbacks.
- Are my files uploaded anywhere?
- No. Conversion runs entirely in your browser using the Canvas API. Files never touch our servers, which matters for pre-publication work, client assets, or anything sensitive.
