RGB Channel Splitter
Inspect and export the red, green, and blue components of any browser-supported image with accurate per-pixel channel separation.
Upload an image to separate its red, green, and blue channel values.
Three independent channel previews
Render red, green, and blue values from the same source pixels at matching dimensions.
Grayscale or channel color
Use grayscale to compare intensity or channel color to see each component in its native hue.
Individual PNG downloads
Download only the red, green, or blue result without creating a problematic ZIP archive.

Reading RGB image channels
Each RGB channel stores intensity values from 0 to 255. In grayscale mode, brighter areas contain more of that channel. Color mode keeps the selected component in red, green, or blue while setting the other two components to zero.
常見問題
Why do channel images look grayscale?
Grayscale makes channel intensity easier to compare: white is 255 and black is 0.
Does the splitter keep transparency?
Yes. Each output PNG keeps the source alpha value for every pixel.
