Convertisseur Gratuit en Ligne JBG vers AVIF

JBG is a lossless format used to store both black and white, and color images. It was developed by JBIG (Joint Bi-level Image Experts Group) for compressing pictures to send by fax but can also be used quite effectively on other images. Moreover, it offers better compression than the earlier G3 and G4 standards.

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.
