About this tool
Colour printing at a cyber café or print shop can cost five times more than black & white, and some offices only accept grayscale scans. This tool redraws each page in shades of grey so what you see is exactly what the printer will produce.
Pages are converted to images in the process, so text is no longer selectable. Pick 200–300 DPI for documents with small print, or 110–150 DPI for a smaller file to email.
Frequently asked questions
Will the text still be selectable?
No. Pages become grayscale images. Keep your original if you need to copy text.
Does it make the file smaller?
Scanned colour PDFs usually get smaller. Text-only PDFs may grow, because text becomes an image.
Can I preview before printing?
Open the downloaded PDF — it shows exactly how a black & white printer will print it.
