Decoded by your browser's native AV1 decoder — nothing uploads

Your browser may not decode AVIF — Chrome, Edge, Firefox 93+, or Safari 16+ recommended

AVIF decoding uses the browser-native ImageDecoder API; encoding uses canvas. Your file is never uploaded. Animated AVIF converts using its first frame.

How it worksPage 2

Why AVIF needs converting — and why decode support is the whole game

AVIF (AV1 Image File Format) compresses photographs at roughly half the size of JPEG with 10-bit color and HDR support — but the software around you has not caught up: most desktop apps, many CMS pipelines, older Office builds, and a long tail of photo tools still refuse .avif files. Converting to PNG (lossless, universal), JPEG (smallest universal lossy), or WebP (modern web default) is a decode-then-encode job, and the decode side is where tools fail — AV1 decoding in native code requires shipping a large codec library. Browsers have already solved this: Chrome 85+, Edge, Firefox 93+, and Safari 16.1+ all decode AVIF natively, and the WebCodecs ImageDecoder API exposes it with frame-accurate control. This tool uses that native decoder (with an <img> fallback), so there is no codec download, no WASM bundle, and the conversion of a 4K image takes milliseconds. Animated AVIF files convert using their first frame — a fair trade for a still-image format.

The browser's built-in AV1 decoder does the heavy lifting — no codec download needed.

The hero image the CMS rejected — Tomo's conversion

Tomo's designer ships the new hero image as AVIF to save bandwidth, but the CMS upload validator only accepts PNG, JPG, and WebP.

  1. Convert:He drops the 3.1 MB AVIF and picks WebP q92 — the browser-native decoder renders it in milliseconds, no upload, no queue
  2. Compare:The WebP lands at 4.8 MB for the 3840×2160 image; PNG would have been 11 MB. The preview panel confirms zero visible difference from the AVIF original
  3. Archive the original:He keeps the AVIF as the CDN master — it still halves bandwidth — and uploads the WebP copy wherever the CMS demands it
  4. Standardize:The team bookmarks the tool for every future AVIF hand-off; the whole loop costs seconds instead of an ffmpeg install

To convert AVIF without installing a codec: drop your file in, pick PNG, JPG, or WebP, and download — the browser decodes it locally and nothing is uploaded.

AVIF in 2026: Ubiquitous Browsers, Patchy Everything Else

AVIF compresses photographs at roughly half the JPEG file size with 10-bit color and HDR support, and every current browser decodes it natively. The gap is everywhere else: desktop photo apps, CMS upload validators, older Office builds, and countless internal tools still reject .avif files. That asymmetry is why conversion remains a daily need — the web can consume AVIF, but the software downstream often cannot. This converter bridges the gap using the decoder your browser already has: WebCodecs ImageDecoder draws the pixels, canvas re-encodes them, and nothing ever uploads.

Choosing Between PNG, JPG, and WebP Output

The three outputs serve three destinations. PNG is lossless and supports transparency — the right choice for graphics, screenshots, and anything you will edit further, at the cost of large files for photographs. JPEG is the universal legacy format: every tool since 1992 opens it, and quality 90-95 is visually transparent for photographic content. WebP is the modern middle ground: lossy compression close to AVIF efficiency with universal browser support, making it the default recommendation when the goal is "smaller file the CMS accepts". The quality slider applies to JPG and WebP; PNG always encodes losslessly.

What AVIF Conversion Cannot Preserve

AVIF supports 10-bit and HDR color; canvas encoders output 8-bit standard dynamic range, so HDR masters are tone-mapped to SDR — the image looks correct on ordinary displays but is no longer HDR. Animation reduces to the first frame. And by definition, converting to any larger format gives up AVIF compression: a converted JPEG is bigger than the source AVIF, not smaller. Treat the AVIF as the master asset for the web and the converted copy as the compatibility hand-off — keep both, and re-convert from the master when a new destination appears.

Frequently Asked Questions

How does the conversion work without uploading?

Your browser already ships an AV1 image decoder (Chrome 85+, Edge, Firefox 93+, Safari 16.1+). The tool feeds your AVIF bytes to the native ImageDecoder API — with an img-element fallback — draws the decoded pixels to a canvas, and re-encodes to your chosen format with canvas encoders. No codec download, no WASM bundle, no upload: the conversion of a 4K image takes milliseconds.

Which output format should I choose?

PNG when you need lossless quality or transparency — largest files. JPG for maximum compatibility with older software, at a quality setting you control (92 is visually transparent for photos). WebP for the modern web: same universal browser support as PNG/JPG with much smaller files. If the destination is a CMS that rejects AVIF, WebP is usually the best-supported compromise.

What happens to animated AVIF files?

The conversion extracts the first frame and produces a still image. Animated AVIF is essentially an AV1 video track in an image container; browsers can decode it, but PNG/JPG/WebP are still formats with no animation (WebP animation exists but is a different encoding path). For animated content, extract the frame you need or use a video converter.

Why is my converted file larger than the AVIF original?

AVIF compresses photographs roughly twice as efficiently as JPEG and significantly better than WebP — that is its whole point. Converting to an older format necessarily gives up that efficiency: a 3 MB AVIF photograph may become 5 MB as WebP q92 or 9 MB as JPEG q92. Keep the AVIF as your archival master and treat the converted copy as the compatibility hand-off.

The conversion fails — what should I check?

First confirm the file really is AVIF (.avif or image/avif type). Then check your browser version: the ImageDecoder path needs Chrome/Edge 85+ or Firefox 93+; Safari 16.1+ decodes AVIF via the img fallback. Very old browsers without native AVIF support cannot decode the format at all — the tool tells you this rather than producing a broken output.
