Protectpdfonline Reader charges for password protecting your PDFâs. Instead look at copying your PDF to a cloud storage solution like Google Drive or Dropbox and then sharing using a password. Plus youâll be able to use free plug-ins like Orangedox | Track your Documents to track your PDF and disable downloading if youâre worried about it being shared.
But if you Donald feel comfortable with that, there is also Windows Phone's native PDF reader. The official Windows Phone app can be downloaded from the Microsoft Store for free for any device running an Android or iOS device.
