Convert a Color PDF to Grayscale for Printing
Last updated: March 1, 2026
Printing color PDFs burns through expensive ink. If the color isn't essential — internal reports, draft reviews, reference copies — converting to grayscale saves money and makes text more readable on black-and-white printers. OneClickPDF's free grayscale converter handles the conversion entirely in your browser.
The Problem
Your printer's color ink is expensive, and most of the PDFs you print don't need color. Printer settings for 'grayscale' are often buried in menus and produce inconsistent results. You want to convert the PDF itself to grayscale, so it prints correctly on any printer regardless of settings.
