About this tool
RGB is for screens, CMYK is for print. The conversion is an approximation because CMYK has a smaller gamut than sRGB, so vivid screen colors often clip when printed.

Frequently asked questions
How do I convert RGB to CMYK?
Paste your RGB value in the field above. The CMYK equivalent updates as you type, with a live color preview and copy button.
Is the RGB to CMYK conversion accurate?
The math is exact, but converting between screen-based RGB and print CMYK is always an approximation. For production print, validate the output against your printer’s ICC profile or proof.
Do you store the colors I convert?
No. Conversion happens entirely in your browser. Nothing is sent to a server and no values are saved.
Can I use RGB values with or without a hash / parentheses?
You can paste a full CSS string like `rgb(255, 107, 53)`, or just the numbers separated by spaces or commas.
When should I use CMYK instead of RGB?
CMYK is required for print: business cards, posters, packaging, and any deliverable that goes to an offset or digital press.
