Need to convert a color PDF to black and white? This tool turns any colour PDF into a clean grayscale (black-and-white) document in seconds. It is ideal before printing on a black-and-white printer, faxing, or archiving - black-and-white pages use less ink and are often smaller in file size.
The conversion runs entirely in your browser, so your color PDF is never uploaded to a server. Text stays sharp and the layout is preserved - only the colour is removed. Whether your file uses American "color" or British "colour", the result is the same: a print-ready black-and-white PDF, free and with no signup.
Uploading a scan to a form with a size cap? Convert it to black and white first, then compress the PDF to an exact size such as 200KB. If the PDF asks for a password when you open it, unlock the PDF before converting - password-protected files cannot be read by the converter.
