Image Combiner & Channel Extractor | Legacy

Important

This is the legacy version of the Image Combiner & Channel Extractor. Looking for a modern and improved version? Check out the updated version here!

Note

This version was recreated to match the original release as closely as possible, due to a loss of the most up-to-date project files. Minor differences may exist.

Image Combiner is a Windows Forms (.NET) application that lets you:

• Combine up to four images into a single RGBA PNG.
• Assign each input to a color channel (Red, Green, Blue, Alpha).
• Extract individual color channels (Red, Green, Blue, Alpha) from an existing image into new files.

Export results as PNG (with transparency).

This tool is designed for game developers and texture artists, who need to pack or unpack texture maps efficiently.

Features

• Import PNG or JPG images for each channel.
• Automatic grayscale conversion of inputs.
• Fast pixel manipulation.
• Preview images before combining or extracting.
• Save outputs as .png (with transparency).
