AVIF Converter — Convert To and From AVIF

AVIF is a next-generation image format that routinely achieves 50% smaller file sizes than JPEG at the same visual quality. This tool lets you convert any JPEG, PNG, or WebP to AVIF, or decode an AVIF file to a more universally compatible format — all inside your browser with no upload required. AVIF output encoding requires Chrome 94+ or Edge 94+; decoding (reading AVIF files) is supported in all modern browsers.

All processing happens in your browser. No data is sent to any server.

Frequently Asked Questions

What input formats does this support?
You can upload AVIF, JPEG, PNG, and WebP files. Drop the file on the upload area or click to browse.
Can every browser output AVIF?
No. AVIF encoding via the Canvas API is only supported in Chrome 94+ and Edge 94+. If you select AVIF output in another browser, you'll see an error. Use WebP as an alternative — it's widely supported and still much smaller than JPEG.
Can every browser open and decode an AVIF file?
Yes. AVIF decoding is supported in all major modern browsers — Chrome 85+, Firefox 93+, and Safari 16+. If your AVIF file won't preview, try updating your browser.
How much smaller are AVIF files compared to JPEG?
Typically 40–60% smaller at equivalent visual quality, depending on the image. Photographic images and smooth gradients see the biggest gains.
Does my image leave my device?
No. All conversion happens in your browser using the Canvas API. No files are uploaded to any server.
