What Is an AVIF File? How to Open and Convert It to JPG
AVIF is a modern image format based on the AV1 video codec that delivers smaller files than JPG or WebP at similar quality, which is why many websites serve it. Modern browsers open AVIF directly; to use it elsewhere, drop it into anyview.dev and click “JPG” or “PNG”.
What AVIF is
AVIF (AV1 Image File Format) is a royalty-free format from the Alliance for Open Media, the group behind the AV1 video codec. At comparable quality it's much smaller than JPG and often smaller than WebP, and it supports transparency, HDR and wide color.
Why your download ended up as .avif
Online stores, news sites and image CDNs automatically send AVIF to browsers that support it. So “Save image as” gives you a .avif file even though it looks like an ordinary photo on screen.
Pros and cons
Pros: very small files, fewer blocky artifacts at low quality, transparency support.
Cons: slower to encode, and many older editors, office apps and upload forms still can't open AVIF.
How to open AVIF
Chrome, Edge, Firefox and Safari (iOS 16 / macOS Ventura and later) display AVIF — just drag the file into a browser tab. Windows Photos depends on installed extensions, and older software may refuse it.
Convert AVIF to JPG or PNG
Drop the AVIF files into anyview.dev and click JPG (opens anywhere) or PNG (keeps transparency). Each result downloads immediately; for several, use “Download all (ZIP)”. To go the other way and make your own images smaller, click the AVIF button instead.

FAQ
Does converting AVIF to JPG lose quality?
With quality set to 90% or higher under “Options”, the difference is barely visible — but the JPG will be larger.
What about animated AVIF?
Support for animated AVIF is limited; when it converts, only a single still image is saved.
