Protecting your PDFs is important because they contain a lot of sensitive information. This includes not only financial documents like invoices but also medical records and other important papers. Unfortunately, there are many ways that your PDFs could be compromised. Hackers can find your unencrypted PDFs by searching for them online or by examining the information you’ve stored in the file. They could even break into your computer and steal your passwords. To protect your PDFs from these threats, you’ll need to encrypt them. Encrypting means scrambling the data within so that only the owner can access it. This will make it nearly impossible for anyone to get at your sensitive information, so you can feel much more comfortable about sharing it with others. There are several different ways that you can encrypt your PDFs, but one of the easiest is to use this PDF Encryption tool.
