About PDF Colour Conversion
Convert the colour space of your PDF to match your output needs:
- Convert between RGB, CMYK, and Grayscale
- Prepare documents for professional printing
- Optimise colours for screen or web viewing
- Preserves document structure and layout
Note: Colour conversion may cause slight colour shifts, especially between RGB and CMYK. This conversion cannot be perfectly reversed.
When to Use Each Colour Space
- sRGB — Web, email, on-screen viewing
- Adobe RGB — Photography, design, wide-gamut displays
- CMYK — Commercial printing, press-ready output
- Grayscale — Black & white printing, smaller files
Tips for Best Results
- Convert to CMYK before sending files to a commercial printer
- Use sRGB for documents viewed primarily on screens
- Grayscale reduces file size for text-heavy documents
- Colour conversion cannot be perfectly reversed — keep your original file
- Adobe RGB is best for photography and wide-gamut displays
