Free Online RLE to RGBO 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.

Format for representing colors in the three primary colors (red, green and blue), each of which has 255 gradations. In contrast to the standard RGB, it allows you to change the transparency of the entire image using the opacity parameter. It is less flexible in terms of transparency settings than RGBA.
