We store important documents in PDF format every day. Contracts, bank documents, and other sensitive information we don’t want in the wrong hands. However, they can be stolen when sent over unsecure connections or if your device is hacked. If you know how to password protect a PDF, however, you can still keep it secure. Here’s how.
Adobe Acrobat is the most popular program to access PDF documents. The DC Pro version can also password protect them:
1. Click File menu in the top-left corner, choose Open, choose your file and open it;
2. Go to File -> Properties;
3. Choose the Security tab;
4. In the Security Method menu, choose Password Security;
5. Tick the box Require a password to open the document and enter your password in the designated field. Be sure to check our tips on how to create a strong password. You can also use a password manager to memorize more complex and safer passwords.
You can also encrypt PDF files with the MacOS Preview app:
1. Click File, choose Open and select the file you wish to encrypt. Open it. It should not necessarily be a PDF file as you will be able to convert it to PDF later;
2. Then go to File -> Export as PDF;
3. Click on Show details for more options;
4. Tick Encrypt and then enter your password in the Password and Verify fields. Click on Save. You can either overwrite the old file or create a new one. Your newly saved file will be password protected.
1. Open MS Word;
2. Click Open tab;
3. Click Browse;
4. Select the document you want;
5. Click File;
6. Choose Save As;
7. Select PDF as the file type;

Unsurprisingly, there are a lot of third-party apps you could use. However, use PDF encryption software under your own discretion – make sure it is safe and does not collect your data.
NordVPN recently released a file encryption application called NordLocker. It uses end-to-end encryption to protect your files. It can protect your PDFs and any other files with powerful encryption. Even if a snooper gets a hold of your files, they won’t be able to read them without a specific key.
