Convert color PDF to black and white
Last updated: 2026-10-08
Render each PDF page as a grayscale image and combine the images into a PDF with the original page sizes. Grayscale values are calculated from the rendered red, green and blue channels. This is a raster conversion: selectable text, links, forms and annotations are flattened. Keep the source if you need editable or searchable content.
