About the PDF to Grayscale / Black & White
PDF Grayscale converts a colour PDF to grayscale or to pure black and white. This is handy for printing on a monochrome printer, saving ink and producing high-contrast copies of scans.
The tool draws every page, converts each pixel to a grey value using the standard luminance weights for red, green and blue, and saves the result as images in a new PDF. In black and white mode every pixel becomes either black or white based on a brightness threshold. As the pages are saved as images, text is no longer selectable and file size can change.
