A black-and-white PDF prints cheaper, looks cleaner for text documents, and cuts colour-ink use. Here's how to convert a PDF to black and white, free and privately.

Why go black and white?

Colour printing is expensive and often unnecessary for text or forms. Converting to black and white (or grayscale) saves colour ink, produces crisp text, and gives a uniform, professional look for documents you'll print or photocopy.

How to convert a PDF to black and white

  1. Open the Print-friendly tool and add your PDF.
  2. Choose the pure black-and-white mode for the lightest ink use, or grayscale for smoother tones.
  3. Preview and download the converted PDF.
Pure black and white uses the least ink and gives the sharpest text. Grayscale keeps subtle shading, which suits documents with photos or diagrams.

Especially useful for dark pages

If your PDF has a dark or coloured background, the print-friendly conversion also flips it to a white background with dark text — saving a huge amount of ink compared with printing it as-is.

Do it privately

The conversion happens in your browser on your device, so your document is never uploaded.
