AVIF Converter
Convert images to AVIF format with adjustable quality for the smallest modern web file sizes.
Convert JPG, PNG, WebP, BMP, TIFF, or GIF images to AVIF with five quality presets (60–100). AVIF uses the modern AV1 codec, producing files typically 50% smaller than JPG and 20% smaller than WebP at equivalent quality. 85 (Recommended) balances visual fidelity with aggressive compression. AVIF supports HDR and transparency. All conversion runs entirely in your browser inside a Web Worker, so your images never leave your device. Note that AVIF is supported in Chrome 85+, Firefox 93+, and Safari 16.4+; older browsers cannot display AVIF directly.

FAQ
Common questions and answers about this topic.
Are my images uploaded to a server?
No. All conversion runs entirely in your browser inside a Web Worker. Your images never leave your device.
Why use AVIF instead of WebP or JPG?
AVIF uses the AV1 codec and produces files roughly 50% smaller than JPG and 20% smaller than WebP at equivalent quality. It also supports wider color gamuts and HDR. The trade-off is that encoding is slower and older browsers (pre-2022) cannot display AVIF, so it is best suited to performance-critical sites that can fall back to WebP/JPG via the <picture> element.
Is AVIF supported on all browsers?
AVIF is supported in Chrome 85+, Firefox 93+, Safari 16.4+, and Edge 121+. Older browsers (Internet Explorer, Safari before 16.4) cannot display AVIF. For maximum compatibility, serve AVIF via a <picture> element with WebP and JPG fallbacks.
