RGBA Channel Packer

Combine grayscale images into a single RGBA texture

How it works

Upload or drag and drop 2-4 grayscale images that will become the Red, Green, Blue, and Alpha channels of a single packed texture. Missing channels will be filled automatically. This technique is commonly used in game development and 3D graphics for efficient texture storage.
