What is the PDF Grayscale Tool and what does it do
The PDF Grayscale Tool converts all colored elements of your document to grayscale. Colors, photos, backgrounds and charts are recalculated to maintain readability but to eliminate colors, making the document look like a printout from a mono printer.
For the user, this means the ability to quickly prepare a black and white version for printing, sending by e-mail or archiving. Instead of fiddling with printer settings or graphics editors, you simply convert the PDF to shades of gray and save it as a new file.

Why you should convert PDF to grayscale online without programs
The easiest way to convert a document to black and white is to use the mono printing option, but you don't always have full control over this. Sometimes the printer uses color ink anyway, and you still see the color in the PDF preview, making it difficult to verify what will end up on the paper.
Webp.pl's PDF grayscale tool solves this problem at the source. You immediately prepare a black and white PDF file that retains the layout but no longer contains colors. Thanks to this, you know exactly what the print will look like, and most printers treat such a document as material prepared for mono printing.
