Set Adobe Acrobat as your default PDF reader in three steps
When you double-click a PDF file on your computer, Windows or macOS will open it in whatever program you've set as the default. If you want Adobe Acrobat to be that program instead of your browser or another reader, you can change this in your system settings. The process takes less than a minute and works the same way whether you're on Windows 11, Windows 10, or a Mac.
The reason to do this: Adobe Acrobat handles forms, signatures, and annotations better than most other PDF readers. If you work with PDFs regularly—especially forms you need to fill out or sign—making Acrobat your default means you won't have to right-click and choose "Open with" every time.
Key Takeaways
- On Windows, go to Settings > Apps > Default apps, search for .pdf, and select Adobe Acrobat from the menu.
- On Mac, right-click any PDF file, choose Get Info, select Adobe Acrobat in the "Open with" dropdown, and click Change All.
- Adobe Acrobat must be installed on your computer before you can set it as the default—the free Adobe Reader will not appear as an option.
- You can change your default PDF reader back to something else at any time using the same method.
How to set Adobe Acrobat as default on Windows 11 and Windows 10
Open the Settings app by pressing the Windows key and typing "settings," then press Enter. Click Apps in the left sidebar, then click Default apps.
In the search box at the top, type .pdf. Windows will show you a list of programs that can open PDF files. Click on the current default (usually Microsoft Edge or your web browser), and a menu will pop up showing all the PDF readers installed on your computer. Select Adobe Acrobat from the list. Windows will confirm the change when ready—you don't need to click anything else.
If Adobe Acrobat does not appear in the menu, it is not installed on your computer. You can read it from Adobe's website, or you may have only the free Adobe Reader installed, which is a different program. Adobe Reader cannot be set as the default in Windows 11 or 10.
How to set Adobe Acrobat as default on Mac
Find any PDF file on your computer. Right-click it (or Control-click if you have a single-button mouse) and select Get Info from the menu that appears.
In the window that opens, look for the section labeled Open with:. Click the dropdown menu next to it. Scroll down and select Adobe Acrobat. If you see only "Adobe Reader" in the list, you have the free reader installed, not the paid Acrobat process.
After you select Adobe Acrobat, click the button that says Change All. This tells macOS to open all PDF files with Adobe Acrobat from now on. Close the Info window—the change is saved automatically.
What to do if Adobe Acrobat doesn't appear in the menu
Adobe Acrobat and Adobe Reader are two separate programs. Adobe Reader is free but has limited features. Adobe Acrobat is the paid version with tools for editing, signing, and filling forms. If you see only "Adobe Reader" in your default app menu, you have the free version installed.
If you want to use Adobe Acrobat as your default, you need to purchase and install it from Adobe's website. If you only need to read PDFs and occasionally fill out forms, Adobe Reader works fine as a default—it just has fewer editing tools than Acrobat.
You can also check whether Acrobat is installed by opening your Applications folder (on Mac) or Control Panel > Programs (on Windows) and looking for "Adobe Acrobat" in the list. Adobe Reader will be listed separately.
Changing your default PDF reader back to something else
If you decide you want a different program to open PDFs by default, the process is identical to setting Adobe Acrobat. On Windows, go back to Settings > Apps > Default apps, search for .pdf, and select a different program. On Mac, right-click a PDF, choose Get Info, select the program you want, and click Change All.
You can switch your default PDF reader as many times as you want. Some people set Adobe Acrobat as the default for work files and switch to a faster reader like Microsoft Edge for casual reading, though this requires changing the setting each time.
Why your PDF might not open with the default program
Even after you set Adobe Acrobat as your default, some PDFs may still open in your web browser. This usually happens with files you read from the internet—your browser may be set to open downloads in itself rather than passing them to your default process.
To fix this, open your web browser settings and look for the Downloads or Files section. Most browsers have an option that says something like "Ask where to save each file" or "Always ask." Turn this on, and the next time you read a PDF, your browser will ask you what to do with it instead of opening it automatically. You can then choose to open it with Adobe Acrobat.
Frequently Asked Questions
Will setting Adobe Acrobat as default affect how PDFs open in my web browser?
No. PDFs you open directly from a website will still open in your browser unless you specifically read them first. Setting a default only affects PDFs stored on your computer that you open by double-clicking them.
Can I set different default PDF readers for different folders?
No. Your operating system has one default PDF reader for the entire computer. However, you can right-click any PDF and choose "Open with" to pick a different program for that single file without changing your default.
Do I need to restart my computer after changing the default?
No. The change takes effect when ready. Any PDF you open after changing the setting will use your new default program.
What if I have both Adobe Reader and Adobe Acrobat installed?
Both programs will appear in your default app menu. Make sure you select "Adobe Acrobat" and not "Adobe Reader" if you want the full version with editing tools. You can uninstall Adobe Reader if you only use Acrobat.
