- Description
- The RL4 file type is associated with the Windows operating system, particularly designed for bitmap images. It specifically refers to a bitmap file format used in Windows environments for storing graphical images in a 4-bit RLE (Run-Length Encoded) format. This compression technique helps in reducing the file size without sacrificing the image quality significantly. RL4 files are typically used for storing simple graphics or icons with a limited color palette, making them efficient for applications where space conservation is important.
- It is an icon image file used to show application icons in the macOS Finder and macOS dock. It contains one or several .PNG images and it supports 1bit and 8-bit alpha channels.
