PDF Secure vs ZipHarbor

Protect your PDF documents with a password. The PDF won't open without the password. It works on any platform. PDF Secure also allows you to completely remove the password protection of a document. Using PDF Secure is very simple: • Select a PDF document from your files • Choose a password (ideally strong) and do not forget it • Export anywhere (Files app, any cloud drive, E-mail, AirDrop, Messages, ...) → The password will now be requested at any attempt to open the PDF (on all platforms) PDF Secure is compatible with the dark mode. And it's 100% free (no in-app purchases, no ads). NO DATA COLLECTION. Everything happens on device. Your privacy matters. Enjoy!
