Convert JPG, PNG, or WebP to AVIF — the newest and most efficient widely-supported web image format. Runs in your browser. Requires Chrome 85+, Firefox 93+, or Safari 16+.
What is Image → AVIF?
AVIF (AV1 Image File Format) compresses better than JPG and WebP — often 30-50% smaller for the same visual quality. It supports 10-bit color, HDR, and transparency. Support is now good across all modern browsers, so the main reason not to use it is legacy compatibility. This tool encodes to AVIF using your browser's native encoder — Chrome 85+, Firefox 93+, Safari 16+.
How to convert images to AVIF
- 1Drop JPG, PNG, or WebP files into the drop zone.
- 2Pick a quality (default 92%).
- 3Click 'Convert to AVIF'. If your browser doesn't support AVIF encoding, the tool will show a clear error instead of silently returning a PNG.
- 4Download the AVIF file(s).
Use Cases
Cutting-edge web performance
AVIF is the current smallest-at-equal-quality format. Use it as the top choice in a <picture> element with WebP and JPG fallbacks.
Hero images and photography portfolios
The gains are largest for large photographs where every byte counts.
Tips & Best Practices
- ▸Encoding is slow compared to JPG/WebP — AVIF trades encode time for smaller output.
- ▸Not every image benefits equally. Small icons often see marginal gains; large photos see the biggest wins.
- ▸If your target audience uses older browsers (Safari <16), pair AVIF with WebP + JPG fallbacks via <picture>.
