Can You Password-Protect a PDF in Microsoft Edge

Microsoft Edge is known as a cross-platform web browser that is powered by AI technology. Surprisingly, it can serve as a PDF reader and editor, providing a set of features for handling PDF files. For instance, it enables you to view PDFs in different modes (like single-page view, continuous scroll, etc.), search words in PDFs, highlight text in PDFs, draw on PDFs, read PDFs aloud, and more.

Can you password-protect a PDF in Microsoft Edge? Unfortunately, Microsoft Edge doesn’t offer a built-in feature to directly password-protect PDFs. Is there no way to password-protect PDFs in Edge? Don’t worry! Although there is no direct way for PDF password-protection, some third-party tools and workarounds are available. Let’s explore the following content!

How to Password-Protect a PDF in Microsoft Edge

In this section, I’ll show you two effective methods to password-protect PDF files in Edge with detailed steps. Now, let’s have a look!

Method 1. Password-Protect a PDF in Edge Using Extensions

Microsoft Edge serves as an excellent web browser, offering many extensions for various purposes. Although it lacks a built-in feature for encrypting PDF documents, it offers various add-ons for PDF encryption. Check the guide below to learn how to password-protect a PDF in Microsoft Edge free.

Step 1. Open your Microsoft Edge browser, click the Extensions icon (if you don’t see the Extensions icon, click the three-dot icon in the top right to select the Extensions option), and choose the Get extensions for Microsoft Edge option.

In addition, you can use an offline PDF program, such as Adobe Acrobat and SwifDoo PDF, to decrypt PDF files. If possible, you can ask the PDF sender to offer the password.
