As a small business owner, you might be looking into how to secure a PDF you share over email. Maybe you’re in the business of selling printables or ebooks, and you’re worried that people are sharing your product freely over the internet. Or maybe you’re nervous about emailing private or sensitive information to a client because you suspect others might have access to their inbox.
Whatever your reason, you’re right to be concerned about internet security. In this day and age, you have to be. After all:
- If content is your product, sharing it in the form of an unprotected PDF file could have a negative impact on your sales. If your content is available for free download online, why would anyone want to pay for it?
- If the information in the documents you send is sensitive, sharing it through unprotected PDF files could cause a data breach. Data breaches can be harmful to your clients in a myriad of ways—depending on the nature of the service you provide and their specific situation, it could even put their livelihood at risk.
How to secure a PDF
Fortunately, there are simple measures you can take to protect your clients’ privacy and the confidentiality of your agreements.
One of the most essential of these measures is password protection: You can set a password to a PDF and then share that password with your client over a telephone call or an SMS. Taking this simple step drastically reduces the chances of an unauthorized person viewing the PDF. Even if they somehow gain access to it, without the password, they won’t be able to see what’s inside.
In addition to restricting who can open a PDF, you can also use password protection to control what can be done to a PDF. You can do this by setting an owner password to the PDF file. When you do that, the PDF is viewable by anyone but edits are restricted to those with a password. This is great for when your concern isn’t that people will view the contents of the file but rather that they will alter it in some way, such as by adding or removing pages or even adding or editing text. You can also use this to prevent others from selecting, copying, or printing the document.
