Printing a colorful PDF on a black-and-white printer often wastes ink trying to approximate colors, or prints inconsistently. This tool converts every page of your PDF to true grayscale so it prints cleanly and predictably on any black-and-white printer. Everything happens locally in your browser — your file is never uploaded.
Every page is desaturated using a standard luminance formula, so colors convert to accurate, consistent shades of gray.
Ideal for saving on color ink/toner when printing reports, contracts, or drafts that do not need color.
Choose Medium, High or Ultra output resolution to balance sharpness against file size.
All processing happens locally in your browser. Your PDF is never uploaded to any server.
No. Each page is rendered as an image and desaturated to grayscale, then reassembled into a new PDF — this is what makes the color-to-gray conversion accurate and consistent across text, graphics and photos alike. As a result, the output is image-based and text is no longer selectable or searchable. If you need to keep editable, searchable text, this tool is not the right fit — it is intended for print-ready output.
Often yes, since grayscale images generally compress smaller than color ones, but that is a side effect — the goal is accurate grayscale conversion, not compression. Use the Compress PDF tool afterward if file size is your main priority.
High is recommended for most documents — sharp enough for printing and reading on screen. Choose Ultra for detailed graphics or photos, or Medium for simple text documents where a smaller file size matters more.
Yes — since every page is rendered as an image regardless of whether the original was scanned or digital, scanned documents convert just as well as digital ones.
