The HEIC is a modern image format with the final specification completed in 2015. The format is a container format which whilst mostly used for storing image data the format can actually support video, audio and text data streams.

HEIC files are binary in nature and offer an alternative to existing digital photo formats such as JPEG featuring better compression whilst retaining comparable image quality. In some cases the file size can be 50% that of the equivalent JPG file.

The AVIF format is an image based container format designed to store image or image sequences which are compressed with the AV1 compression algorithm. The format has been around since 2019 and is based on the HEIF container format and as such it competes with the HEIC image format.

During tests the format has shown to perform better than JPG files not just in the reduced file size but in overall image quality. Support for the format is growing and is already supported in the Chrome and Firefox web browsers. AVIF files can also be opened in many 2D image editing applications.
