File format information for AVIF and WEBP

Extension	AVIF
Full Name	AV1 Image File Format
Type	Image
Mime Type	image/avif
Format	Binary
Opens With	Paint.Net

The AVIF file format is aimed at being a modern replacement for the popular JPEG image format. Developed by the Alliance for Open Media, AVIF is an advanced image file format that leverages the cutting-edge compression algorithms used by the AV1 video codec.

The aim of the format is to surpass the quality of the equivalent JPEG file while packing a smaller file size via the use of the AV1 compression algorithm. The aim of the compression algorithm, which is a lossy algorithm, is to reduce the file size by removing detail from the image that the eye would not normally notice, thus reducing the size of the final AVIF file.

Support for AVIF files is still growing, with many modern image editors able to read and write to the format. The latest versions of the most popular web browsers have also moved to support AVIF images, having seen the benefit to website developers of reduced image sizes and thus reduced bandwidth usage.

Extension	WEBP
Full Name	WebP
Type	Image
Mime Type	image/webp
Format	Binary
Opens With	Paint.Net, Photoshop

A WebP file is a next-generation image file format designed for the web. It allows large and highly detailed photographic-quality images to be stored using a very small file size, making it an ideal format for use by websites where bandwidth comes at a premium.

It's aim is to replace other photographic formats, such as JPEG, by offering similar levels of compression and quality while offering a superior reduction in file size. As well as storing static images, the WEBP format can also store animations, making it a great alternative to the traditional animated GIF format.

As the WEBP format is still relatively new, support for it is best found in modern image editing applications or those that benefit from regular updates.
