Convert a PDF to black and white
Make a document print cleanly in mono, without uploading it.
For printing, a black-and-white document is cheaper and often clearer than colour. This tool removes the colour from your PDF in the browser, so it is never uploaded, and the result prints cleanly in mono.
How to convert a PDF to black and white
- 1
Add your PDF
Drop in the colour document.
- 2
Convert
The colour is removed on your device, leaving grayscale.
- 3
Download and print
Save the mono PDF, ready for a black-and-white printer.
Why convert locally
Removing colour in the browser keeps the document on your device, so a file bound for the printer is never uploaded first.

No. It runs in your browser and the file never leaves your device.
Will photos still be visible?+
Yes, photos become grayscale rather than disappearing.
