PDF to Grayscale online, free and without limits
Color printing costs several times what black and white does, and many office printers charge per color page whether or not the color mattered. Converting to greyscale first means a 40-page report prints at the cheaper rate without anyone remembering to change a driver setting. It also helps when a document must be faxed, photocopied or archived, where color adds size without adding information.

Questions about PDF to Grayscale
What people usually want to know before they upload a document.
Does the text stay searchable after conversion?
No. Greyscale conversion renders each page as an image, so the text layer is not carried across. Keep the color original for searching and use the greyscale copy for printing.
What resolution should I choose?
150 DPI is right for ordinary office printing. Choose 300 DPI for documents with fine print or detailed diagrams, and lower values only when the file must be very small.
Will this reduce my file size?
Usually yes, because color information is discarded — though at high DPI a rasterized page can be larger than a text page was. Run Compress PDF afterwards if size is the priority.
