AVIF viewer — open an AVIF image right here

Got an AVIF your photo app won't open? Drop it here and see it instantly. AV1 decodes natively in modern browsers, so the image renders on your machine — no install, no upload.

Your file never leaves your device — viewing runs in your browser. 0 bytes uploaded.

In short

AVIF (AV1 Image File Format) stores AV1-coded pixels in an ISO base-media box container. Because AV1 decodes nativelyin current browsers, this viewer simply hands the file to the browser's decoder and draws the result — a real, truthful render — along with the image's pixel dimensions. It's the fastest way to look at an AVIF someone sent you when your desktop photo app throws an "unsupported format" error. Nothing is uploaded, and you can prove it in the Network tab.

Why AVIF often won't open — and why it does here

AVIF is a young format, so a lot of software hasn't caught up. Windows Photos without the AV1 extension, older macOS Preview, most desktop image editors, and plenty of phone galleries either refuse AVIF outright or show an empty thumbnail. Almost always the file is perfectly healthy — the viewer is what's out of date. Browsers moved much faster: Chrome, Firefox, Edge and recent Safari all ship a native AV1 image decoder, which is exactly what this page uses. So an AVIF that your computer's built-in apps can't touch will usually display here without a problem.

What this viewer does and doesn't do

It decodes and displays. It reports the file name, size, format and the decoded pixel dimensions. It does not produce a download, edit the image, or change the file on disk — it's a viewer, not a converter. If you want a saveable copy in a format older software accepts, use the sibling converters linked below. One honest note on how the render looks: the browser presents the image through an 8-bit sRGB canvas, so a 10/12-bit HDR or wide-gamut AVIF is tone-mapped for display here — the underlying file still holds its full range.

Why "no upload" is verifiable, not a slogan

The AVIF is read with the browser's file APIs and decoded by the same native AV1 support browsers use to display AVIF on the web — all on your machine. No request carries your image. Don't take it on faith: open DevTools, select the Network tab, drop a file, and watch nothing leave. It's the same principle as ourzero-upload proof page, applied to viewing. The free photo ceiling is 50 MB; larger files prompt a plain message rather than an upload.

If it won't render, it may be damaged

A viewer can only show an image the browser can decode. If your AVIF was truncated by an interrupted download, carries a garbage prefix from a recovery tool, or has a broken box structure, the AV1 decoder will refuse it — and we won't fake a preview. The viewer runs a local structural scan and, when it finds damage, links you torepair AVIF to rebuild the container first. Repair it, then view the repaired copy here.

FAQ

How do I open an AVIF file?

Drop it above. Modern browsers decode AV1 — the codec inside AVIF — natively, so the image renders right on this page, along with its pixel dimensions. There's nothing to install and no account to create. If a program on your computer refuses to open the AVIF, it usually just predates the format; a current browser can display it.

Why can't I open AVIF on my computer normally?

AVIF is relatively new, so older photo viewers, image editors and operating systems don't recognise it yet — you'll see an "unsupported format" error or a blank thumbnail. The file is almost always fine; the software is just older than the format. This viewer leans on the browser's own AV1 decoder, which is up to date, so it can show images your desktop apps can't.

Can I download or convert the image here?

This page is view-only — it renders the AVIF so you can see it, but it doesn't produce a file. If you need a downloadable copy in a universal format, use the AVIF to JPG converter (smaller, universal, lossy) or the AVIF to PNG converter (lossless, keeps transparency). Both run in the browser exactly like this viewer.

The image is broken or won't render — what's wrong?

The viewer reads the file locally and, if the browser's AV1 decoder refuses it, tells you which case you have. Genuine container damage — from a truncated download or a recovery tool — is flagged and linked to the AVIF repair page. A structurally intact file that still won't decode usually just needs a newer browser. We never fake a preview of an image the browser couldn't decode.

Is the file uploaded to view it?

No — 0 bytes leave your device. Open DevTools, switch to the Network tab, drop your AVIF, and confirm nothing is sent. The image is read and decoded entirely in your browser.
