Color Channel Separator — Split an Image into RGB, CMYK, YCbCr & LAB Channels
Split any image into its individual color channels and download each as a grayscale plane. Choose RGB, CMYK (print separations), YCbCr (video / JPEG), or CIELAB — all computed in your browser, nothing uploaded.
Split any image into its individual color channels and download each one as a grayscale plane. Choose RGB, CMYK print separations, YCbCr (the space used by video and JPEG), or CIELAB — every channel computed in your browser with nothing uploaded. It is a window into how an image is built from its components.

Frequently Asked Questions
How do I separate an image into RGB channels?
Select the RGB mode and the tool produces three grayscale images — one each for red, green, and blue — that you can view and download. Bright areas in a channel show where that color is strongest.
Can I get CMYK separations for print?
Yes. The CMYK mode splits the image into cyan, magenta, yellow, and black plates, which is useful for understanding how artwork will separate on a printing press.
What are the YCbCr and LAB modes for?
YCbCr separates brightness from color the way JPEG and video do, which is handy for compression and chroma work. CIELAB splits an image into a lightness channel and two perceptual color axes, useful for color science and editing.
Are the channels computed on my device?
Yes. Every channel split runs in your browser, so the image is never uploaded.
