Convert all pages to grayscale (black & white)
Convert every page of a color PDF to grayscale (black and white). This is useful when you need to print on a monochrome printer without unexpected muddy tones, want to reduce ink costs for a large print run, or need a grayscale version for a filing system that requires all documents in black and white.
Perceptual Conversion
Uses a weighted luminance formula (Rec. 601) that matches how the human eye perceives brightness, producing natural-looking grayscale.
Full Document Processing
All pages are converted in a single pass -- no need to process pages individually.
High-Resolution Output
Pages are rendered and converted at 2× scale to preserve detail in the grayscale result.
