Most of the time, you may find it important to save documents to PDF in black and white or in grayscale.
For instance, converting documents to grayscale enables you to print a PDF on a monochrome printer or save colored ink when using a color printer. In such documents, all text and images lose their color information and take on corresponding shades of gray.
Saving the resultant file size is another benefit in having PDF in grayscale. That is, if a PDF file contains many color images and file size is essential but color isn’t, the conversion saves space. If a PDF will be printed in B/W then converting it allows you to visually check what the end result will look like.
To produce PDF documents in B/W or Grayscale, right-click any file in windows explorer and go to ‘Pdf Output Settings >Pdf Output tab’ and check ‘Output PDF as Grayscale’ option as highlighted in the screenshots below.
