What is Image to AVIF?

Convert images to next-gen AVIF format. Next-gen AVIF — up to 50% smaller than WebP at the same quality. Push image performance to the limit on supported browsers. An AVIF file with HDR-capable color and alpha support.

All processing happens locally in your browser. Your images are never uploaded to any server.

Key Features

Best-in-class compression for 2025+ browsers
Supports 10/12-bit color, HDR, film grain
Still serves a WebP/JPG fallback to older browsers

Common Use Cases

Delivering next-generation image format for the smallest possible file sizes on modern websites
Encoding photos and graphics with both lossy and lossless compression plus alpha transparency
Future-proofing image delivery for high-DPI and 4K displays without bandwidth bloat

User Guide

How to use this tool

AVIF is a next-generation image format based on the AV1 video codec. It routinely produces files 30–0% smaller than WebP and up to 70% smaller than JPG at equivalent visual quality. This tool converts your JPG, PNG, and other sources into AVIF locally, without uploading a single byte.

How to use it

Drag your source image into the drop zone. The tool decodes it, redraws it on a canvas, and instructs the browser to encode the pixels as AVIF. Because AVIF encoding is computationally expensive, large images may take a few seconds to render.

Use the quality slider to trade off between file size and fidelity. AVIF holds up remarkably well at very low bitrates, so you can usually go 5–0 percentage points lower than you would with WebP or JPG for the same perceived quality.

Best-in-class compression among widely-supported image formats
Full transparency support (alpha channel)
Excellent color fidelity even at aggressive settings
Ideal for hero images, product photography and photo blogs

Compatibility considerations

AVIF is supported in Chrome, Edge, Firefox and Safari 16+. For older browsers, use the HTML picture element to declare an AVIF source with WebP and JPG fallbacks. Most CDNs (Cloudflare, Vercel Image Optimization, imgix) can serve AVIF automatically when the browser advertises support.

If your browser does not yet ship the AVIF encoder, the tool will surface an error message. In that case, use the WebP converter instead — the visual quality gap is small in most real-world cases.

Frequently Asked Questions

Is AVIF production-ready?

Chrome, Firefox, Edge and Safari 16+ all ship AVIF support (~90% of users). Use <picture> to serve fallbacks.

When should I pick AVIF over WebP?

When bytes are at a premium — hero images, product photos, or heavy editorial pages.

AVIF vs WebP — which is better?

AVIF generally produces 20–30% smaller files than WebP at equivalent quality, but encoding is slower and support is slightly less universal (Chrome, Firefox, Safari 16+, Edge). Use AVIF as the primary format with WebP as fallback.

Does AVIF support transparency?

Yes. AVIF supports alpha channel transparency in both lossy and lossless modes, making it ideal for logos, icons, and product images with transparent backgrounds.

Is AVIF supported on Safari?

Safari 16+ (macOS Ventura, iOS 16) supports AVIF. For older Safari versions, serve WebP or JPG as a fallback using the <picture> element.

Is this tool free to use?

Yes. This tool is completely free with no sign-up, no watermarks, and no daily limits. All processing runs locally in your browser.

Why is AVIF encoding slow?

AVIF uses the AV1 codec, which is optimized for maximum compression rather than encoding speed. This is intentional.

Can I encode animated AVIF?

This tool encodes still AVIF only. For animation, WebP or MP4 are better options today.
