Method 1: Uncheck Always Open This File Option
Chrome lets you automatically launch certain file types as soon as they’ve finished downloading locally. If you want to stop Chrome from launching a certain file type in its default program automatically, change the settings from the downloads panel. Here’s how.
Step 1: Open Chrome. Once the file is downloaded or has started, click the Download icon in the menu bar.
Step 2: Here, right-click on the downloading or downloaded file. Then, click on the Always open files of this type option.

You can also use the above steps to stop any other file type from opening automatically on Chrome. If the file is still downloading, it will not be automatically opened once the download is finished.
Tip: If you’re running an older version of Chrome, open Settings > Downloads. Click on Clear next to Open certain file types automatically after downloading. This will clear Chrome download preferences.
Method 2: Remove the Relevant Extension
Certain Chrome extensions will automatically launch selected file types, like PDFs, once they finish downloading. To stop that from happening, disable the relevant extension on Chrome. Follow the below steps to do it.
Step 1: Open Chrome and click on the three-dot icon in the top-right corner. Then, go to Extensions and click on Manage Extensions.

Step 2: Here, turn off the toggle for the relevant extension.

Repeat this process and ensure extensions, such as Adobe PDF Reader extension, are turned off. You can also remove the relevant extension from Chrome permanently.
Bonus: Stop Chrome PDF Downloads From Opening Automatically
