How to Export and Install Chrome Extensions (.crx) Without the Web Store

If you have access to the internet, downloading extensions directly from the Chrome Web Store is the best option. However, if you cannot access it, you can use pre-packaged .crx extensions shared by others. Here is a method to export Chrome extensions (.crx).

Export Extension (.crx)

Open Chrome Browser > More Tools > Extensions, or directly enter chrome://extensions/ as shown in the screenshot below.

Enable Developer Mode in the top right corner.

Get the Extension ID. For example, for "IDM Integration Module", the ID is ngpampappnmepgilojfohadhhmbhlaek. Record this ID first, then click "Pack extension".

You can use a simple search tool like Everything to find the extension's directory by searching for the ID. Open the directory and copy the path.

Return to "Pack extension", enter the full extension path, and click OK. A prompt will appear showing the export path for the .crx file.

Install Chrome Extension (.crx)

If you have access to the internet, you can search and install directly from the store. For those without access, you can install the exported .crx extension. First, switch to the Extensions page by entering chrome://extensions/ in the Chrome browser (this is crucial; you must be on this page to install). Then, simply drag the .crx file onto this page.

Summary

This method allows you to share exported Chrome extensions with users who cannot access the store. However, there are potential issues: the extension may not receive timely updates, and since it hasn't been reviewed by Google, you might download malicious software provided by others. Use this method with caution.
