PDF to grayscale

Convert a colour PDF to grey — each page rendered at ~144 DPI, recoloured, and rebuilt as a new PDF.

The file stays in this browser. Each page is rendered at about 144 DPI, recoloured to grey, and rebuilt as a new PDF.

Encrypted, signed, and form PDFs are not supported. Up to 25 MiB and 60 pages. The output is raster (image) pages — text is no longer selectable or searchable, and file size can grow. For prepress-grade gray conversion use a print shop.

How to use

  1. Choose a PDF.
  2. Convert.
