Free Online RLE to AVIF Converter

This is a format that applies an 8-bit encoding to images for the purpose of compression and transportation. The format was originally developed for the Utah Raster Toolkit software package for managing bitmaps. The compression algorithm provides a replacement for repeating strings of bytes into pairs, which significantly reduces the file size.

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.
