How to Convert a PDF to Black and White to Save Ink

Colour printing is expensive, and many offices and print shops charge extra for it. Some organisations also ask for black-and-white submissions. Converting your PDF to grayscale handles both.

Why convert before printing?

• Save ink and money: colour toner costs far more than black.
• Predictable results: see exactly how charts and photos will look on a mono printer before you print.
• Requirements: some exams, courts and offices request grayscale documents.

Check your charts

Charts that rely only on colour can become hard to read in gray. Red and green lines, for example, may look almost identical. Preview the result and, if needed, add labels or patterns in the original file.

Smaller files too

Removing colour can also reduce file size. For even smaller files, follow with Compress PDF.
