Convert a PDF to grayscale (black and white)

Turn a colour PDF into black and white. Grayscale documents are cheaper to print, often required by print shops and exam boards, and easier to read when photocopied.

Every page — text, photos and charts — is converted to shades of grey.

How to use it

  1. Add your PDF. Choose the colour document.
  2. Click Process. Each page is converted to grayscale.
  3. Download. Print or share the black-and-white copy.

Good to know

  • Save on colour ink. Printing in grayscale uses only black ink or toner.
  • Check your charts. Colours that look different can become similar greys, so make sure graphs still read clearly.
  • Text becomes part of the image. Pages are redrawn, so text can't be selected afterwards.
  • Private by design. Your file is processed inside your own browser. It is never uploaded to a server, so nobody else can see it.

Frequently asked questions

Why can't I select text after converting?

Each page is redrawn as a high-resolution grayscale image to guarantee no colour remains.

Will the file be bigger?

It can be for text-only PDFs. Use Compress PDF afterwards if you need a smaller file.

Can I convert only some pages?

Extract those pages first, convert them, then merge the document back together.
