Black and White, the Easy Way
Color is not always what you want in a PDF. You might be printing on a black-only printer, trimming a file down for email, or just preferring a clean black and white look for a report or a scan. Doing it by hand in a PDF editor is fiddly and often paid.
This tool converts the whole document to grayscale for you. It redraws each page in shades of gray, shows you a live preview so you can check the result, and rebuilds the file ready to download. You pick the quality, from a smaller standard file to a sharper high-resolution one.
Because each page is redrawn as a gray image, the saved PDF is image based rather than selectable text, which is the trade-off for a clean, consistent conversion that runs entirely in your browser. Your file never leaves your computer.

FAQ
Frequently Asked Questions
Common questions about converting PDFs to grayscale.
How does it convert a PDF to grayscale?
It renders each page, converts the colors to shades of gray using standard luminance values, and rebuilds the PDF from those gray pages. The result is a clean black and white version of the original.
Will the text still be selectable?
No. Because each page is redrawn as a gray image, the saved PDF is image based, so the text is no longer selectable. This is the trade-off for a consistent grayscale result in the browser.
What does the quality setting do?
It controls the resolution each page is rendered at. Standard keeps the file small, while High and Maximum render at higher detail for sharper text and images at the cost of a larger file.
Does grayscale make the file smaller?
Often yes, especially for color-heavy PDFs, since color data is removed. Very high quality settings can offset that, so choose Standard if file size matters most.
Is it good for printing?
Yes. A grayscale PDF prints cleanly on black-only printers and avoids using color ink, which is useful for drafts and documents you do not need in color.
Is this grayscale PDF tool free?
Yes, it is completely free with no signup and no limits. Everything runs in your browser, so your file stays on your device.
