What is AVIF?
AVIF is appearing on more websites and in more saved images. This guide explains what the format is, why older apps cannot open it, and how to get a compatible JPG or PNG.

What is AVIF
AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec. It offers efficient compression and supports transparency, HDR and animation. For websites, AVIF helps reduce page weight without a noticeable quality loss.
Major browsers and services support the format, so it appears more often in search results and on modern sites. But the newer the format, the higher the chance an older app cannot open it.
How to open AVIF
The easiest option is a modern browser: current versions of Chrome, Firefox, Edge and Safari display AVIF. On Windows, the built-in viewer may need an update or extension. On macOS, support depends on the OS version.
Image editors vary: GIMP and Photoshop need recent versions or plugins. If you need to open the file quickly in an office suite, for print or in an older program, converting is the safer route.
When to convert AVIF to JPG or PNG
- To JPG — when you need a universal format for sending, publishing and older devices.
- To PNG — when transparency or lossless editing matters.
- Keep AVIF — when the file is used only on a modern website and saving bandwidth is the priority.
Our AVIF to JPG and AVIF to PNG converters decode the image in your browser. If the browser cannot handle AVIF, server-side processing takes over and the file is deleted automatically.
Limitations
Animated AVIF files are currently processed as the main frame. Images with an extended colour gamut may look slightly different after conversion to JPG.
Questions and answers
Is AVIF a photo or a video?
It is an image format based on the AV1 codec. It supports both still images and animation, but it is most often used as a regular image.
Why can't I open AVIF?
The format is relatively new and older software does not recognise it. Modern browsers support AVIF, while Windows and some editors may need an update or a codec.
Is AVIF better than JPG?
AVIF usually compresses better: smaller files at comparable quality. JPG is still safer for compatibility, older devices and print workflows.
Is transparency preserved when converting?
PNG keeps transparency. JPG cannot store it, so transparent areas become white.
