I use M.S. Office Lens at work every week. You can free-crop photos, compose into PDF, reorder pages, etc and save to OneDrive which quickly gets a phone PDF onto my desktop. Brilliant! OfficeLens also had an app you could load on desktops. I’m sure it was for tablets, but the ability to take a photo, free-form crop and save to PDF was fantastic. Alas, my old install of the app still works, but won’t convert to PDF anymore.
