Grayscale PDF
Renders every page and converts it to true grayscale (luminance), then rebuilds the PDF at the same page sizes — ideal for mono printing or removing colour. Honest scope: pages become images at the dpi you choose, so text is no longer selectable; the tool says so and reports the dpi.
A little guidance. A better result.
How to use Grayscale PDF
Every page rendered and converted to true luminance grayscale at your dpi; pages become images, and it says so.
Prepare your input
Open a PDF and choose rendering resolution.
Use the workspace
Convert the pages to grayscale.
Check your result
Check small text, page count and output size.
Know the limits
Pages become images and text is no longer selectable. Colour removal does not guarantee a smaller PDF.
