Convert PDF to grayscale online — black and white, still sharp
Printing on a black and white printer, saving colour ink or submitting a document that must be monochrome? Our Grayscale PDF tool turns every colour in your PDF into the same shade of gray: text, shapes, gradients and pictures. Unlike tools that turn each page into a photo, it changes only the colours, so text stays sharp, selectable and searchable, and the file doesn't balloon in size. The black and white PDF opens in the Mega AI Studio, ready to download.
True grayscale
Text, shapes, gradients and pictures all become gray.
Text stays text
Nothing is flattened — you can still search, select and copy.
Small files
Only the colours change, so the file stays about the same size.
