Frequently Asked Questions
- How do I convert a PDF to CMYK?
- Upload your RGB PDF, choose FOGRA39 (or another print colour profile), click Convert, and download a print-ready CMYK PDF in seconds. No software or signup needed.
- What is FOGRA39?
- FOGRA39 (ISO Coated v2) is the standard colour profile for European offset printing on coated paper. Most European print shops require or recommend it for professional print work.
- Why does my printer require CMYK?
- Print shops use CMYK inks (cyan, magenta, yellow, black). If your PDF is in RGB (screen colours), the printed colours may look different from what you see on screen. Converting to CMYK with the correct profile ensures the printed result matches your design.
- Will I lose colour quality converting to CMYK?
- Some vivid RGB colours (especially neon blues and greens) cannot be reproduced exactly in CMYK — that is a physical limit of printing ink. We use ICC-based conversion that preserves colours as faithfully as possible within the CMYK gamut.
- Which colour profiles are supported?
- We support FOGRA39 (standard EU coated), FOGRA47 (uncoated), GRACoL (US coated) and more. FOGRA39 is the right choice if you are unsure and printing in Europe.
