Split a PNG into CMYK Channels
Convert an image into its CMYK components — Cyan, Magenta, Yellow, and Key (black) — each as a grayscale PNG showing that ink's coverage. It's the model print uses, so this is a quick way to preview how an image separates into plates. Drop a file and download the four channels as a ZIP, processed in your browser.

What each channel is
- Cyan / Magenta / Yellow — how much of each ink a pixel needs; white = full coverage, black = none.
- Key (K) — the black plate, which adds depth and saves coloured ink.
An honest caveat about print colour
This is a mathematical RGB-to-CMYK conversion, not a colour-managed one. Real print separations depend on the specific paper and press profile (an ICC profile), so treat these channels as a useful preview and analysis aid, not final print-ready plates. For production, convert through your print shop's profile in a colour-managed application.
FAQ
Can I use these for professional printing?
As a preview, yes; as final separations, no — production CMYK needs the press's ICC profile. This tool gives a standard, profile-free conversion for inspection and design work.
Why is the Key (black) channel mostly white on a dark image?
White here means "lots of this ink." A dark image needs heavy black, so its Key channel is bright. Light images have a mostly-black (empty) Key channel.
