Convert PDF to Grayscale
Pages are rendered, desaturated and rebuilt. Like compression, this replaces the text layer with an image.

What it will not do
- Output pages are images, so text is no longer selectable.
Where this runs
Convert PDF to Grayscale runs entirely inside this page. Your file is read by the browser, processed in memory and handed back to your downloads folder. It is never sent to a server, because there is no server involved in this tool.
