Good to know

Is the result suitable for color-critical print proofing?+

No. Accurate print-to-screen conversion depends on ICC profiles, paper and ink. This tool provides an unprofiled numerical approximation.

Are my files uploaded?+

No. Processing happens on this device. The tool may download its own code, but source files and output are not sent to a processing server.
