Adobe bundles the Acrobat Chrome extension with Adobe Acrobat Reader DC so that you can easily open PDFs in Reader while browsing the web. Once installed and enabled, the extension will:
- Open PDF files in the Acrobat Reader desktop app.
- Offer a consistent and reliable PDF viewing experience.
- Provide access to all the tools you need to add comments, fill forms, and sign PDFs.
Note:
You can easily disable the extension at any time. The extension does not read the content of your PDFs or any content on the sites you visit.
The extension is not installed automatically with Acrobat Reader. If Acrobat Reader is the default PDF owner on your computer, you're prompted to install the extension when you launch Acrobat Reader. Once the extension is installed, you must activate it before use.
When you open a PDF in Chrome, you see the Adobe Acrobat prompt in the upper-right corner of the window. Click Open in Acrobat Reader.
