About AV1 Image File Format
Common Use Cases
- Upgrading web images to the latest compression standard
- Further reducing page weight beyond WebP
- HDR content delivery
WebP was a major step forward from JPG and PNG, but AVIF takes compression efficiency even further. Built on the AV1 video codec, AVIF consistently outperforms WebP in independent benchmarks while supporting HDR, wide color gamut, and transparency.
WebP uses the VP8 codec while AVIF uses the newer, more efficient AV1 codec. At equivalent perceptual quality, AVIF files are typically 20-30% smaller than WebP.
Why Convert WebP to AVIF?
20-30% smaller than WebP
AVIF offers meaningful file-size savings even over WebP. For image-heavy pages, the cumulative bandwidth reduction can shave seconds off load times.
Better gradient and skin tone handling
AVIF produces fewer banding artifacts on smooth gradients and skin tones compared to WebP, resulting in more natural-looking photographs.
HDR and 10-bit color
AVIF supports 10-bit and 12-bit color depth natively. If your source images contain HDR data, AVIF preserves it while WebP is limited to 8-bit.
Future-proof format
AVIF is backed by the Alliance for Open Media (Google, Apple, Mozilla, Netflix, and others). It is positioned as the long-term successor to both JPG and WebP.

Frequently asked questions
- Is WebP to AVIF conversion free?
- Yes. Free users get a daily allowance, registered accounts get higher limits, and Premium or Lifetime members get unlimited conversions.
- Will I see a quality difference?
- At default settings, the AVIF output is visually identical to the WebP source. You may notice subtle improvements in gradient smoothness due to AVIF handling banding better.
- How much smaller will the file be?
- Expect 20-30% savings compared to the WebP source, depending on image content. Photographs with complex textures tend to see the biggest gains.
- Does AVIF support animation like WebP?
- AVIF supports animated sequences, but tooling and browser support for animated AVIF is less mature than for animated WebP. For animated content, WebP or GIF may still be more practical.
- Do all browsers support AVIF?
- Chrome, Firefox, Safari 16+, and Edge all support AVIF, covering over 95% of global traffic. Use WebP as a fallback for older browsers.
- How long are files kept?
- All files are auto-deleted within 1 hour. We never share your data with third parties.
- Is there a size limit?
- Yes, the maximum is 500 MB per file.
