Convert color PDF pages to black and white — save ink when printing.
PDF to Grayscale is a free online tool that converts all color content in your PDF to black and white. Every page is rendered and converted using luminance-weighted grayscale (the ITU-R BT.601 standard used in professional imaging). The result is a high-quality grayscale PDF that looks great when printed and significantly reduces ink or toner usage. Perfect for printing documents, presentations, and reports in black and white. Runs entirely in your browser.
