How to change your default PDF viewer.

Learn how to change the way your computer opens PDF files, so you can take full advantage of editable features and more.

Perfect for sharing, the PDF is one of the most popular file formats in use today. Most operating systems have a PDF viewer that will let you easily open these documents so you can read files, share them, or make small edits. To get the most out of your PDFs, though, you may want to switch your default viewer to Adobe’s Acrobat PDF viewer, which is more feature-rich because it’s designed specifically for PDFs.

Make the most out of your PDFs.

Whether you’re using a Windows or macOS operating system, your computer will automatically open any PDF with its own default app. For Windows, that’s Microsoft Edge. For macOS, it’s Preview. Here’s how to change the default PDF viewer for each of these operating systems.

Change from Microsoft Edge to the Acrobat PDF viewer:

  1. Right-click on the thumbnail of any PDF file.
  2. On the menu, click Properties.
  3. A new dialog box will appear. In the first subsection, the text “Opens with:” indicates which PDF viewer is set as your default. Click the Change button.
  4. Select Adobe Acrobat DC or Reader from the list as your default.
  5. Click OK to save and apply changes.

Change from Preview to the Acrobat PDF viewer:

  1. Right-click on the thumbnail of any PDF file.
  2. On the menu, click Get Info.
  3. Navigate to the Open With: section and select Adobe Acrobat DC or Reader from the drop-down list.
  4. Tap Change All to apply this change to all future PDF documents. Tap Continue to finish.

Now you can view, mark up text, and more with all of the additional capabilities unique to Acrobat. For a quick and easy way to manage PDFs — including adding comments and signatures — you can use a free online editor to help keep important documents moving.
