It's nice app to protect your pdf files. Just select the pdf file you want to protect, then type any password you want to use to encrypt the file, retype the same password, then click 'Add password' then enter file name. You will see password protected file in' Result.' or in your 'Download' folder. Thanks to developer.👍

I dont know why people are commenting its not working. I think they dont know how to use it. I would like to say that you have select first which pdf u want to add password. Than create two password owner and one more . Keep it same or different. But if you keep it different in two boxes the file can we open with any of those two passwords. And you to have save the file. See in RESULT the original file will remain without pw. But which u saved here will be protected.

Always quits as soon as I select a pdf file to be secured. Android 11. Cannot give meaningful rating until this is fixed.
