You have a brand HEX or RGB colour and you need its CMYK build for a print job. The picker above runs the real ICC profile conversion in your browser — same math Photoshop uses. You can also upload your print shop's own ICC profile to soft-proof against it.
Real ICC profiles, not an approximation
This page bundles the actual ICC profile files (sRGB v4 and the destination CMYK profiles) and runs them through Little CMS compiled to WebAssembly — the same colour-management engine that powers Firefox, GIMP, and most Linux print pipelines. Numbers match Photoshop at the same profile + perceptual intent. Every other free converter on the web skips the ICC engine and silently assumes sRGB → US SWOP.
Bundled profiles: sRGB v4 (ICC, freely distributable), U.S. Web Coated (SWOP) v2 and Coated FOGRA39 / ISO 12647-2:2004 (Adobe Color Profile Bundling Agreement).
Bring your own ICC profile
Most pro print shops have their own ICC profile that captures their exact press, paper, and ink behaviour. Click ↑ Upload your shop's ICCin the profile picker to run the conversion against it. The file is parsed entirely in your browser — Polotno never sees it, no copy is uploaded. We're the only free web converter that does this; for any other tool you'd need Photoshop or Affinity.
