Grayscale refers that the file that used to be in full colors is represented by gray shades. If you have a ton of colored PDFs, turning color to grayscale will bring you some benefits. Grayscale PDFs only consume black ink and save colored ink when printing them. Besides, it would be faster to print those documents than colored ones. What’s more, when the PDF is converted to black and white, the document size is much smaller, freeing up disk space and expediting file transfers. Want to know how to change PDF from color to grayscale? In this article, I will teach you how to realize it with two simple yet effective online converters.
