Why Convert JPG to AVIF?
AVIF (AV1 Image File Format) is the newest image format gaining broad browser support. Based on the royalty-free AV1 video codec, AVIF delivers dramatically better compression than both JPG and WebP.
At the same visual quality, AVIF files are typically 40-50% smaller than JPG and 20-30% smaller than WebP. This makes AVIF ideal for performance-critical web applications, especially on mobile networks.

Browser Compatibility Note
AVIF is supported in Chrome 85+, Firefox 93+, Safari 16.4+, and Edge 85+. If this converter produces an empty or very small file, your browser may not support AVIF encoding via the Canvas API. In that case, try using Chrome or Edge for the best results. You can also use our JPG to WebP converter as an alternative next-gen format with broader encoding support.
Common Use Cases
- Maximum web performance — AVIF offers the best compression ratio of any widely-supported image format.
- Mobile-first sites — dramatically reduce image data transferred on cellular connections.
- Progressive enhancement — serve AVIF to browsers that support it, with JPG or WebP fallbacks for older browsers.
- High-quality photography — AVIF handles gradients and fine detail better than JPG at low file sizes.
Frequently Asked Questions
Are my files uploaded to a server?▾
No. Everything runs in your browser. Your images are never sent anywhere.
Is AVIF better than WebP?▾
For compression efficiency, yes — AVIF produces smaller files at the same quality. However, AVIF encoding is slower and browser support is slightly narrower. For maximum compatibility, WebP is safer. For maximum compression, AVIF wins.
Why is AVIF encoding slow?▾
AVIF uses the AV1 codec which is computationally expensive. Browser-based encoding can take a few seconds per image, especially for large files. The resulting files are significantly smaller, which makes the wait worthwhile for web assets.
What if my browser doesn't support AVIF?▾
If your browser can't encode AVIF, the conversion may produce an error or a broken file. Use Chrome (85+) or Edge for the most reliable results. As a fallback, our JPG to WebP converter offers a similar improvement with broader support.
