    Convert an RGB PDF into a four-colour (CMYK) PDF the way printers ask for it: colours separated into cyan, magenta, yellow and black, text black preserved, images kept at full resolution. The tool accepts PDF, ZIP files and works straight from your browser: nothing to install, no account to create.

    Under the hood, the work is done by Ghostscript, converting every colour to the CMYK process space and declaring /DeviceCMYK throughout the document. Vectorizing turns pixels into geometry: the result stays sharp at any scale and can be used in CAD, laser cutting or on a CNC machine.

    Your files are processed on our European servers and then wiped automatically: they are never read, never kept, and never reused to train anything.

    When is this tool useful?

    • Vectorize a logo for engraving or cutting
    • Bring a scanned drawing back into CAD software
    • Prepare a file for a CNC machine or a laser cutter
    • Convert a line drawing for large-format printing

    Frequently asked questions

    Is this a real CMYK file?

    Yes: every fill, text and image is converted, and the output declares only /DeviceCMYK — no RGB left. That is what a printer's preflight checks.

    Which CMYK profile is used?

    Ghostscript's generic CMYK profile, which suits the vast majority of print jobs. A printer who requires a specific press profile (Fogra, SWOP) will supply it; that is a separate, custom conversion.

    Do you keep my files?

    No. They are deleted automatically from our servers shortly after processing, along with the output file and the download link.

    Do I need an account?

    No, the tool works right away. An account is only needed to lift the daily limits.

    Does the result carry a watermark?

    Never. We add no mark of any kind to the files we produce, including on the free plan.
