Common uses

When Convert PDF to Grayscale is useful

Create a grayscale raster copy of every PDF page.

01

Prepare a monochrome print reference copy.

Practical help

Questions before you run it

Is text still selectable?

Will the PDF become smaller?

Not necessarily; rasterization can increase size.

Are signatures retained?
