This app is a handy tool for recovering passwords and content from PDFs. It helps you find a forgotten password for PDFs.
This app uses the pattern you enter to find your PDF password. If you remember part of the password, alphabet, or number pattern, you can find the password with this app. If you do not remember anything, this app does not help much. If you expand the pattern to reduce the number of cases, you can find the password you just forgot. You can also use this app to check the strength of your PDF password.
