}Page guide
Export separate red, green, blue and alpha planes. Combine edited grayscale planes into a new image.
How to use Split and combine image channels
- Choose split mode with one image, or combine mode with three or four grayscale images.
- In combine mode, select the image to use for each channel.
- Run the tool and download the channel planes or combined PNG.
Useful next steps
Separate planes you can edit
Each split plane is an opaque grayscale PNG. Its brightness records that channel’s original byte values, including the alpha plane.
Explicit channel assignment
Combined planes must be opaque grayscale images with matching dimensions. Assign the selected images to red, green, blue and alpha, or choose opaque alpha. No resizing is performed.
