What is a .avif file?
File extension details and usage information
AVIF (AV1 Image File Format) is a modern image format that leverages the AV1 video codec for superior compression and image quality compared to older formats like JPEG. It is designed to be a royalty-free and open-source alternative, offering significant file size reductions while maintaining visual fidelity. AVIF supports a wide range of features, including support for both lossy and lossless compression, animation (similar to GIFs), alpha channel transparency, and high dynamic range (HDR) imagery. This makes it suitable for a variety of applications, from web graphics and photography to archival purposes. The format is gaining increasing support across web browsers and operating systems due to its efficiency and open nature. Its ability to handle complex images with smaller file sizes contributes to faster loading times and reduced bandwidth consumption, particularly beneficial for image-heavy websites and applications. AVIF is based on the ISO Base Media File Format (ISOBMFF), which provides a flexible and extensible container for storing image data and metadata.
