Frequently asked questions

How much smaller is AVIF compared to JPEG?

AVIF typically produces files 40% to 55% smaller than JPEG while maintaining the same visual quality. This is significantly better than WebP, which usually saves 25% to 34% over JPEG.

Why does AVIF conversion take longer than other formats?

AVIF uses a more advanced compression algorithm based on the AV1 video codec. This makes encoding slower, especially in the browser using WebAssembly. Expect a few seconds per image depending on file size and your device.

Is AVIF supported by all browsers?

AVIF is supported in Chrome, Firefox, Safari version 16 and above, and Edge. It covers over 90% of current browser usage. For older browsers, you can serve a JPEG or WebP fallback using the HTML picture element.

What quality setting should I use for AVIF?

Start with quality 60. This usually gives results similar to JPEG quality 80-85 but with much smaller file size. Adjust higher if you need maximum quality or lower if you want even smaller files.

Are my files uploaded to a server?

No. All conversion happens locally in your browser using WebAssembly. Your images never leave your device.
