Google Chrome's built-in PDF viewer can make opening PDFs super-quick. Unfortunately, you don't have access to all of the same tools you can use in apps like Adobe Reader.
So how can you choose to download or open PDFs in standalone apps rather than the browser window. It's a quick fix
Follow these steps:
Step 1: Open Chrome and type "chrome://plugins" into the status bar.
Step 2: Scroll down and find Chrome PDF Viewer.
Step 3: Click the "Disable" link to prevent PDFs from loading within Chrome.
That's it! Now you can choose to download or open PDFs with the standalone reader you have installed on your PC. And if you ever change your mind, the option will be in the same place with an "Enable" link to bring it back.
