What is an AVIF file?
An AVIF file is an image saved in the AV1 Image file format developed by the Alliance for Open Media. It contains compressed image data, similar to a .JPEG or .PNG file. The AV1 Image format was designed as an alternative to the JPEG, PNG, and .WEBP formats.
In 2015, several high-profile tech companies, including Amazon, Cisco, Google, Intel, Microsoft, Mozilla, and Netflix, formed the Alliance for Open Media. This non-profit workgroup began developing a number of open source media technologies and standards, including the AV1 video codec. Eventually, the workgroup realized that the AV1 codec could be applied to images saved in the .HEIF file format. This allowed the workgroup to create the AV1 Image format, which can be used to save high-quality, compressed images within files that are the same size as lower-quality JPEGs. Notably, AVIF files contain less blocking, blurriness, and other visual distortions as similarly-sized JPEGs.
As of late 2020, many companies have begun using or adding support for AVIF files. Notably, Netflix has begun using AVIF files internally, Google has added AVIF support to the Google Chrome web browser, and Microsoft has provided users with a codec that can be used to view AVIF images in programs like Microsoft Paint. More companies and programs are expected to add support for AVIF images as the AV1 Image format becomes more popular.
How do I open an AVIF file?
You can open an AVIF file in Google Chrome (cross-platform) and in Microsoft Paint after installing the AV1 Video Extension (Windows). By 2021, other web browsers will likely support opening AVIF images. Advanced users can use the open source libavif library (cross-platform) to encode and decode AVIF images.
