How to Convert a Coloured PDF to Grayscale (Free)
Remove colour from PDF documents and convert to grayscale. Works on any PDF — reports, presentations, scanned documents.
FixMyPDF's grayscale converter removes all colour from a PDF, replacing it with corresponding shades of grey.
Steps
Go to fixmypdf.in/tools/grayscale-pdf. Upload the colour PDF. Click Convert. Download the grayscale version.
For Printing
Many office printers default to colour mode and charge per colour page. Sending a grayscale PDF to a printer that has colour disabled (or printing as "black only") ensures consistent black-and-white output with no colour ink usage.
For Publishing
Books and documents published in print often need a grayscale version for standard print and a colour version for digital. Convert the final colour PDF to grayscale for the print edition.
