This site provides many functions for PDF editing, however, it works a little bit slowly and it provides too many steps to let people finish managing a file, which we think the developers could make some improvements on it.

Tips for Protecting PDF Files

Apart from redacting PDF to protect the important data, there are other solutions which you can use to prevent your documents from being copied and modified.

To be able to do this, you could make use of a PDF editor to do so, and here we take ApowerPDF as an example. Download it and check the methods below.


Protection Tab
  1. Add opening password. On ApowerPDF, go to “Protection”  – “Encrypt with Password” to enter password under “Document Open” section. Once set, confirm and save the PDF file. In this way, other people could not open your document only when you provide the opening password to them.
  2. Encrypt with permission password. Other people could only perform the specific actions to the PDF file you allow them to do, if you set a permission password. This means they may not be able to edit or copy the content of your PDF file. To do so, also go to “Encrypt with Password” under the “Protection” tab, and then set permission password under “Permissions” section. Also, you need to save the document then the settings will be applied.

You could even add both opening password as well as permission password to one PDF.
