Creating and Using Profiles

(This page deals with establishing entirely separate data directories for running parallel instances of the Chrome browser. To create separate user accounts within the same Chrome browser instance, please read about the multiple accounts feature.)

By creating and using multiple profiles, you can do development — creating extensions, modifying the browser, or testing the browser — while still being able to use Google Chrome as your default browser. We recommend that you use the default profile for your everyday browsing. The details of how to create and use a profile vary by platform, but here's the basic process:

  • Create a folder to hold data for the new profile.
  • Create a shortcut or alias that launches the browser, using the** --user-data-dir** command-line argument to specify the profile's location.
  • Whenever you launch the browser, use the shortcut or alias that's associated with the profile. If the profile folder is empty, the browser creates initial data for it.

Instructions: Windows

To create a profile

  1. Create a folder on your computer, say C:\chrome-dev-profile. This folder will hold the data for the new profile.
  2. Make a copy of the Google Chrome shortcut on your desktop. (Right-click, then Copy.) Name the new shortcut something like Chrome** Development**.
  3. Right-click the **Chrome Development **shortcut, choose Properties, and paste **--user-data-dir=C:\**chrome-dev-profile at the end of the **Target **field. The result might look like this: “C:\Documents and Settings\me\Local Settings\Application Data\Google\Chrome\Application\chrome.exe” --user-data-dir=c:\chrome-dev-profile
  4. Start Google Chrome by double-clicking the **Chrome Development **shortcut. This creates the profile data.

To use the profile

Just start Google Chrome by double-clicking the **Chrome Development **shortcut. Yep, it's that easy.

To clear the profile

You might want to clear the profile if you‘re testing, and you want to start from scratch. Here’s how:

  1. Close Google Chrome.
  2. Delete the contents of your profile folder — the folder you specified with --user-data-dir (for example, C:\chrome-dev-profile).
