Set Microsoft Edge as Your Default PDF Viewer

If your primary goal is simply to view and read PDF files, Microsoft Edge is a capable, pre-installed alternative that handles large files efficiently.

You do not strictly need Adobe Acrobat to display PDF files. Modern web browsers like Microsoft Edge come with built-in PDF engines that are highly optimized for fast loading and secure viewing.

While Edge offers a smooth reading experience and basic annotation tools, keep in mind that it may lack advanced features like complex form filling, digital signatures, or deep editing capabilities found in premium PDF editors.

Open Windows File Explorer and navigate to the folder containing your large PDF document.

2
Open the Context Menu

Right-click on the PDF file, hover your cursor over the 'Open with' option, and click on 'Choose another app'.

3
Select Microsoft Edge

Scroll through the list of available applications and select 'Microsoft Edge'.

Set as Default

Check the box at the bottom that says 'Always use this app to open .pdf files', then click 'OK' to save your new default viewer preferences.

Frequently Asked Questions

Why does Adobe Acrobat X freeze when opening large files?

Adobe Acrobat X is an older, legacy software that lacks modern optimization techniques. When it encounters highly complex or massive PDF files, it can quickly exhaust allocated system memory, causing the application to become unresponsive or freeze.

Can I use Microsoft Edge to edit my PDF files?

Microsoft Edge provides basic annotation tools, allowing you to draw, highlight text, and add simple text comments. However, it cannot replace a dedicated PDF editor if you need to modify existing text, alter images, or manage interactive forms.

Are free PDF viewers secure enough to use?

Yes, modern free PDF viewers like Microsoft Edge and WPS Office are generally very secure. They receive regular updates to patch vulnerabilities and protect your device from malicious code that might be hidden inside downloaded PDF documents.
