Free Online JNX to AVIF Converter

JNX is used by Garmin devices for storing files to display satellite maps available through a BirdsEye subscription. JNX is the so-called tile format which means that a large raster image of the map is divided into smaller rectangular pieces for faster display by the navigator.

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.
