What Protecting a PDF with a Password Means for Your Files

Why should you protect a PDF file with a password? Is it worth your time? Absolutely!

Here are the main reasons why it’s important to protect a pdf file with a password:

  1. PDF Compliance – you should make sure that your PDF is password protected if it includes any sensitive information that’s protected by GDPR regulations. Otherwise, you can be fined for enormous amounts of money;
  2. View and modification restriction – when a PDF is protected by a password, other users who may see it in a common database cannot view and edit the document. That’s why we recommend password protection if you want to prevent anyone from editing the document accidentally or intentionally. Content integrity is very important when you need to use a particular version of a PDF;
  3. Sharing protection – even if a PDF file is password protected, it can be shared against your will. However, the password may protect the information from being copied or changed by other users if they don’t know how to breach through PDF passwords.

Using the PDFLiner online platform, you can create a PDF document or upload one, and protect PDF with a password when the work is done. The service provides a comprehensive set of tools for creating, editing, converting, and sharing your PDF documents.
