Favicon File

An AVIF file is an image saved in the AV1 Image File Format — a modern, highly compressed format used across the web. It holds the same kind of photo or graphic a JPG would, but at roughly half the file size. The catch: it's new enough that some older apps and devices can't open it yet, which is usually why you landed here. If you just downloaded an image and it saved as something ending in .avif that won't open, you're in the right place. This guide explains what the file is, why you're suddenly seeing them, and exactly how to open one on Windows, Mac, iPhone, Android, and Linux — plus the one fix that works everywhere.
