What is an AVIF file?

AVIF files mostly belong to GIMP. AVIF files are image files that use the AV1 codec for compression.
Main Features:

Efficient Compression: They use the advanced AV1 compression technique, similar to methods in MP4 containers, to produce smaller file sizes without losing detail.

MP4-based Structure: Internally, these files rely on an MP4-like format that supports sophisticated data handling.

Software Compatibility: Updated image viewers and editors such as GIMP and modern web browsers can open AVIF files.

This format is designed for high performance in web and application environments, supporting features like transparency and high dynamic range.
FilExt.com tip: If your application does not support AVIF natively, consider using conversion tools or updating your software.

How to open AVIF files

You need a suitable software like GIMP to open an AVIF file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your AVIF file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a AVIF file directly in the browser:.

AVIF file format:

Every file has a defined file format, i.e. how the data is arranged in the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. So you need a detailed analysis of a file to find out the format and the associated program. Below is our analysis of the AVIF files:

The file type was created recently. The following keywords are characteristic: infe, pict, pitm, meta, ftypavif, avifmif, !hdlr, iloc, ispe, (iinf, #iinf, av1C, av01Image and ipco.
