HEIC files are a highly compressed bitmap image file format created specifically to offer greater compression ratios than other formats, such as JPEG, while maintaining image quality. The HEIC format is a standard format created by the MPEG group and has gained support from some major players in the industry, including Apple.

Within an HEIC file, the image data is compressed using advanced compression algorithms that try to maintain image quality while drastically reducing the amount of storage space required. Image data can be stored in either lossy or non-lossy formats, with the lossy format offering the best compression ratio.

With HEIC files being used by Apple in their range of smart phones and tablets, HEIC has become widely adopted and is supported by many image and photo editing software. For applications that do not support HEIC yet, we have an array of HEIC converters that can convert to and from many other image formats.

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.
