Texture channel packer

Pack texture channels cleanly and optimally, for free, in your browser:)

1. Drag and drop your individual channel images into the tool
2. Select the desired texture parsing for each channel
3. Choose the exported channels at the top: R, RG, RGB, or RGBA.
   • R exports the red channel as a single-channel grayscale PNG
   • RG exports the red and green channels to a grayscale+alpha PNG
   • RGB/RGBA export color PNGs with or without alpha as you know them

The tool does some lossless png compression behind the scenes as well and saves the png in the smallest format. Optical grayscale uses OKLab to create a correct grayscale that matches what the eye sees.

Performance note: Very large textures can take noticeably longer to compress. If you’re iterating, test at lower resolutions and re-export final at full size.
