Why convert PDF to Grayscale?
Save Ink & Toner: Printing in black and white is significantly cheaper than color. By converting your PDF to grayscale before printing, you ensure that no color ink is used, even for "black" areas that might otherwise be composed of multiple colors.
Reduce File Size: Grayscale images generally have smaller file sizes than full-color ones. This makes your PDF easier to email and faster to load on mobile devices.
Professional Appearance: Many official documents, academic papers, and legal filings require or look better in high-contrast black and white.
Better Accessibility: Grayscale documents can sometimes be easier to read for people with certain types of color vision deficiencies.
