Image Combiner & Channel Extractor

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).

Prerequisites

  • Windows OS
  • .NET 8.0
