AVIF

AV1 Image File Format

AVIF is the youngest, but most efficient and advanced codec for image compression. AVIF file size is 10 times smaller than JPEG with the same image quality. AVIF supports not only Standard Dynamic Range (SDR) images but also High Dynamic Range (HDR) and Wide Color Gamut (WCG). It can store both image items and image sequences. AVIF is a HEIF conformant format. Netflix has published the first AVIF image in 2018, but still only a few software support it.

HEIF

High Efficiency Image File

HEIF is a container that can be a single image or a sequence of images which makes it ideal for Apple's Live Photos. It is based on HEVC (High Efficiency Video Coding). The format is more convenient than the old JPEG mostly because it is twice smaller despite the fact that is has excellent quality. Therefore you can storage more images on your Apple device which is great. HEIF was developed in 2013 by MPEG (Moving Picture Experts Group) but has become popular only when Apple decided to replace JPEG with it in 2017. However, not so many programs are able to open it which is why you might need to convert it to another format.
