Converting a PDF to black and white, or more precisely to grayscale, turns every color into a shade of gray while keeping the layout, text and images intact. The most immediate benefit is printing: a grayscale PDF prints in monochrome, which costs noticeably less than color and avoids nasty surprises when a printer switches to color cartridges just to render a single logo.
Turning a PDF grayscale also brings consistency. For archives, scanned files or documents meant to be kept for a long time, a uniform look is easier to read and more neutral than a mix of pages in clashing colors. Removing color also neutralizes distracting elements — loud highlights, tinted backgrounds, oversaturated charts — and refocuses the reader's attention on the content itself.
As a bonus, dropping color information frequently reduces the file size, since each pixel no longer needs to store its color components. The effect depends on the document, but a grayscale PDF is generally more compact than its color original.
To go further, chain it with compress to shrink the file even more, then web-optimize if you plan to publish it online for faster loading. And if you want to trim useless margins or keep only a specific region before converting, crop lets you reframe each page.
