I tried both recently on a scanned, color document recently. pdfsandwich gave me really unpleasant, monochrome, and blown out results; ocrmypdf did what I expected, giving me a searchable pdf.

Looks great.. I'm just trying to find the Windows binary?

Maybe use their docker image?

This Docker app looks useful, thank you.

And people say Linux doesn't have any programs :P

I've been using ocrmypdf on Windows through WSL very successfully. Works perfectly.

Looks like there isn't any

It's great and I use it almost every day: paperless-ng uses it in the background.
