How to Stop Microsoft Edge From Opening PDF Files

Why are your PDFs opening in Edge when you want to use another app? Windows may have assigned Microsoft Edge to the .pdf file type, and Edge also has its own built-in PDF reader for files you open from websites.

But those are two separate settings. Changing the Windows default controls PDFs stored on your computer. Changing Edge’s PDF setting controls what happens when you click a PDF link online. We’ll walk through both, using the Smallpdf Desktop App as your new default reader

Microsoft Edge can read local, online, and embedded PDF files. If it is assigned to the .pdf file type in Windows, double-clicking a PDF from your desktop, Downloads folder, or File Explorer will open it in Edge.

To stop Edge from opening PDFs stored on your computer, install the Smallpdf Desktop App for Windows, then make it the default app for .pdf files.

Step 1: Install the Smallpdf Desktop App

• Go to the Smallpdf Desktop App for Windows page or click on the download button below

• Select “Download App.”

• Open the downloaded installer and follow the prompts on your screen.

• Start Smallpdf once the installation is complete.

• Open a PDF in the app to check that it is working correctly.

The desktop app includes a PDF reader and works offline. You can use it to display, print, and share PDFs, as well as handle tasks such as compressing, converting, merging, splitting, and organizing documents.

Step 2: Set Smallpdf as the Default PDF App in Windows 11

1. Open “Start,” then select “Settings.”

2. Go to “Apps” and choose “Default apps.”

3. Type “.pdf” into the search box for file types.

4. Select the app currently assigned to .pdf files. This will often be Microsoft Edge.

5. Choose “Smallpdf” from the list.

6. Select “Set default” or confirm the change when Windows asks.

Close Settings, then double-click a PDF stored on your computer. It should now open in Smallpdf.

Step 3: Set Smallpdf as the Default PDF App in Windows 10

The steps here are similar, although the labels may look slightly different:

1. Open “Start” and select “Settings.”

2. Go to “Apps,” then “Default apps.”

3. Select “Choose default apps by file type.”

4. Scroll down to “.pdf.”

5. Select Microsoft Edge or the current PDF app beside it.

6. Choose “Smallpdf.”

You can also search for “default apps” from the Start menu if you can’t find the setting manually.

What to Do if Smallpdf Doesn’t Appear

Open the Smallpdf app once, then return to Default apps and search for .pdf again. Windows sometimes needs the newly installed app to run before it appears in the list.

If it is still missing, restart your computer and check again. Reinstall the app from the official Smallpdf Windows page if the installation didn’t finish properly.

Changing this setting won’t change your main web browser. Edge can stay as your default browser while Smallpdf handles PDF files.

The PDF reader itself is free, so you can make Smallpdf your default app without paying for Pro. If you want to do more with your files, start a 7-day Smallpdf Pro trial. This gives you unlimited access to 30+ Smallpdf tools to try before committing to a subscription.

You changed the .pdf default, but a PDF link on a website still opens in an Edge tab. Annoying, yes, but it also has a straightforward explanation.

Windows default apps control files opened from your computer. Edge’s built-in PDF reader controls online PDFs and PDFs embedded in web pages. That is why a downloaded file may open in Smallpdf while the same document opens inside Edge when you click its website link.

To stop PDFs from opening in Edge online, change the PDF document setting inside the browser.

Tell Edge to Download PDF Files

1. Open Microsoft Edge.

2. Type ‘edge://settings/content/pdfDocuments’ into the address bar and press Enter.

3. Turn on “Always download PDF files.”

4. Close any PDF tabs that are already open.

5. Return to the website and select the PDF link again.

Edge should now download the file instead of displaying it in its own reader. Open the download, and Windows should send it to Smallpdf because that is your default PDF app.

You can also reach this setting through Edge’s menus. Open “Settings,” go to “Cookies and site permissions,” and find “PDF documents.” The wording or position may change slightly between Edge versions, so the address-bar route is usually faster.

Check Each Edge Profile

Edge settings can apply to individual browser profiles. If you use a personal profile and a separate work profile, repeat the PDF setting in both.

Look at the profile icon near the top of Edge before making the change. A PDF may download in one profile and still open in a browser tab in another because their settings don’t match.

Check How the Website Delivers the PDF

Some websites show documents inside their own viewer rather than sending you directly to a PDF file. In that case, changing the Windows default app won’t replace the website viewer.

Look for a “Download,” “Save,” or down-arrow button on the page. Once the PDF is saved to your computer, open it from Downloads and it should use Smallpdf.

Protected PDFs from a work portal may also be required to open in Edge. Company permissions can decide which app handles the document, especially when the file comes from a managed cloud service. Ask your IT team before changing security or browser policies.

Check That You Opened the Downloaded Copy

Although not common, it is still possible to get confused and open the same browser tab again instead of the copy saved on the computer. Open File Explorer, go to Downloads, and double-click the PDF there.

If the local file opens in Smallpdf, your Windows setting is correct. Only Edge’s treatment of online PDF links still needs attention.

Windows and app updates won’t always change your PDF default, but a repair, reinstall, account policy, or new app prompt can ask you to choose again. You can’t prevent every change, especially on a managed computer, but a few easy checks will help you restore your preferred settings.

Keep Smallpdf Installed and Open It After an Update

Windows can only assign .pdf files to an app it can find. Keep Smallpdf installed. Open it once after a major app or Windows update if it disappears from the default-app list.

You can bookmark the Smallpdf Windows download page in case you need to reinstall it later. Use the official installer rather than an old copy saved elsewhere, so you get the current version.

Don’t Accept the Wrong Default-App Prompt

An app may ask whether you want to make it your default PDF reader. Read the prompt before selecting “Yes,” “Always,” or “Set default.” One quick confirmation can replace your existing .pdf association.

If you only want to open one PDF in Edge, choose a one-time option rather than making it the default for every PDF.

Recheck Both PDF Settings

After a large update, run two small tests:

• Double-click a PDF from File Explorer to check the Windows default.

• Select a PDF link in Edge to check whether the browser downloads it.

If the first file opens in Edge, reset the .pdf association in Windows. If only the online link opens in Edge, revisit ‘edge://settings/content/pdfDocuments’.

Ask IT About Managed Settings

A greyed-out option, a “managed by your organization” message, or a setting that changes back after every restart usually points to an administrator policy. Edge includes business policies that can require PDFs to open inside or outside the browser, while Windows administrators can control default file associations.

On a work or school computer, ask IT to assign Smallpdf as the approved PDF app or explain which reader you must use. Repeatedly changing the setting yourself won’t help if a policy overrides it.

Once your default is set, you can open PDFs in Smallpdf and use the PDF Reader when you need a browser-based option. For other jobs, Edit PDF lets you change document content online, while Compress PDF can reduce a file before you email or upload it.
