Convert a PDF to grayscale
Make a black-and-white copy of a colour PDF — handy for printing without colour ink or for forms that must be in black and white.
Files stay in this browser tab. Close the page and they are gone.

Questions
Will the text stay selectable?
No. Each page is redrawn as a grayscale image, so the text can no longer be selected or searched. Keep your original if you need the text.
Which quality should I choose?
Standard (150 dpi) is fine for reading and most printing. Choose high (300 dpi) for small print or detailed drawings.
Are my files uploaded anywhere?
No. The tool runs entirely in your browser, so your files never leave your device and nothing is kept after you close the page. You can check it yourself: once the page has loaded, turn on airplane mode — the tool keeps working.
Is it free? Is there a file limit?
Yes, it is free, with no sign-up and no watermark. There is no upload limit because nothing is uploaded; very large files are limited only by your device’s memory.
