PDFs are the most common attachments in the email after docs. These lightweight, presentable documents are excellent for communication, research, information, statistics, or literary work. However, despite the easy flow of information they allow, PDFs can often be responsible for data leaks.
Amidst this, since encryption is the best method of maintaining privacy and security, precaution entails encrypting your PDF file while enclosing sensitive information.
Encrypting your PDF documents is somewhat easy, and various online tools are available. But do you want to upload your sensitive data on a website for any random stranger to store it? Even if it is for the “noble purpose” of encrypting it, what makes you sure the site owner won’t try to exploit it? After all, they don’t owe you to protect your data; you blindly trust them.
So, the best course of action is to take power into your hands and proceed with manual efforts, to prevent data loss.
