How to Password Protect a PDF in Microsoft Edge? Full Guide

PDF files are widely used to store and share important information, such as contracts and personal privacy documents, because they can maintain consistent formatting and can be opened on different devices.

However, to prevent these sensitive information from being accessed by unauthorized persons, it is particularly important to password protect PDF files. Next, let's explore how to password protect a PDF file in Microsoft Edge.

How to Password Protect a PDF in Microsoft Edge

Microsoft Edge browser itself allows you to read and edit documents, but it does not have tools to protect them. Although Microsoft Edge itself does not have a native password protection PDF function, we can use third-party extensions to complete this task.

You can search for password protected PDF plug-ins in Microsoft Edge, and you can find many plug-ins for you to choose from.

Step 1. Launch Microsoft Edge on your computer.

Step 2. In the main interface, click the three dots in the top right corner and select Extensions from the drop-down menu.

Step 3. Then, click Get extensions for Microsoft Edge from the drop-down menu.

Step 4. On the Microsoft Edge Add-ons page, type "password protect PDF" in the search box and press Enter. Then, all the related search results will be listed on the page.

Step 5. Here, we choose the first result, like Alto Protect PDF Files by PDFfiller, and click the Get button next to it.

Step 6. Next, you can see a pop-up window with the question “Add Alto Protect PDF Files by PDFfiller” to Microsoft Edge?”, and click the Add extension button.

Step 7. After that, click the Extension icon in the upper right corner and click Alto Protect PDF Files by PDFfiller.

Step 8. Next, click the Choose a file button to upload the PDF file. Please note that the maximum file size is 25MB.

Step 9. After selecting the file, you will be prompted to select a password. Finally, click the Protect File Now button, and your PDF file will be securely protected by a password.

When the extension has finished encrypting the PDF file, you can download it to your computer.

Through the above method, we can effectively password protect PDF files in Microsoft Edge, add a security lock to important information, and make us feel more at ease in our digital life.
