About the Grayscale PDF (black & white)

Turn a colour PDF into grayscale or pure black and white before you print, to save colour ink and get crisp copies. Black and white also makes scanned documents much smaller.

Choose the quality: 150 dpi is right for most printing, 200 dpi for small text, 100 dpi for the smallest file. The pages become pictures, so the text can no longer be selected or searched.

Everything runs in your browser; the PDF is not uploaded.
