Open AVIF images right in your browser - stills, animations, HDR and 10-bit photos, with or without transparency. Zoom to the pixel, see how the file was encoded and save a copy as PNG or JPG. Converting a batch? AVIF to JPG and AVIF to PNG handle many files at once.

AVIF (AV1 Image File Format) is a modern image format from the Alliance for Open Media.
It stores pictures compressed with AV1, a royalty-free video codec, inside the same HEIF container that iPhones use for HEIC photos.
AVIF images are usually noticeably smaller than a JPEG or WebP of similar quality. The format also supports transparency, lossless compression, 10 and 12-bit colour, HDR and animation.
That is why many websites and CDNs now serve AVIF - and why a picture saved from a web page sometimes arrives as an .avif file.
Every current browser can show AVIF, so the simplest way is to drop the file on this page.
Here is how the usual apps handle it.
The Photos app opens AVIF once the free AV1 Video Extension is installed from the Microsoft Store. Without it, File Explorer shows blank icons and older apps refuse the file.
Preview opens AVIF on macOS Ventura (13) and later. On older versions use this viewer or convert the file with AVIF to PNG.
iOS and iPadOS 16 and later show AVIF in Safari and the Files app.
Android 12 and later decode AVIF, so most gallery apps open it. Chrome on any Android version opens it too.
Chrome 85+, Firefox 93+, Safari 16+ and Edge 121+ display AVIF. Current versions play animated AVIF, and frame-by-frame stepping works here in Chrome and Edge.
Open the image here, choose JPG, PNG or WebP under it and press Save.
PNG keeps transparency and every pixel. JPG is smaller and opens everywhere, but has no transparency.
Going the other way? JPG to AVIF and PNG to AVIF shrink your images for the web.
| Format | Based on | Transparency | HDR / 10-bit+ | Animation | Browser support |
|---|---|---|---|---|---|
| AVIF | AV1 video codec | Yes | Yes | Yes | All modern browsers |
| WebP | VP8 video codec | Yes | No (8-bit) | Yes | All modern browsers |
| JPG | JPEG (1992) | No | No | No | Everywhere |
| JPEG XL | JPEG XL standard | Yes | Yes | Yes | Safari; others need a viewer |
Comparing formats on your own pictures? The WebP Viewer and JPEG XL Viewer show the same details, and all file viewers are one click away.
Drop the .avif file on this page, browse for it, or paste it - it opens in a second and nothing is uploaded.
Every current browser can show AVIF, and this viewer adds a built-in decoder for older ones.
Windows Photos needs the free AV1 Video Extension from the Microsoft Store to read AVIF.
Install it, open the file in this viewer, or convert it with AVIF to JPG.
Open the image here, choose JPG or PNG under it and press Save - you get the full-resolution image with the size measured first.
For many files, use AVIF to JPG or AVIF to PNG.
Yes. Animated AVIF stores frames as an AV1 image sequence.
In Chrome and Edge this viewer plays it with pause, speed and frame stepping, and saves any frame as an image. Other browsers show the first frame.
Yes. AVIF can store 10 and 12-bit colour, HDR with PQ or HLG, wide-gamut colour and an alpha channel.
The Info view shows which of these your file uses.
Usually, yes - at similar visual quality an AVIF photo is often smaller than a WebP and much smaller than a JPEG.
The difference depends on the picture and the encoder settings. Use Compare to check an export against the original.
No. The image is decoded by your browser, or by a decoder that runs inside this page.
Nothing is sent to a server.
