Chrome browser can back up history in three ways: 1. Use the built-in export function, open Chrome Settings → History → Export History, save it in HTML or CSV format, suitable for temporary backup; 2. Copy History files (SQLite database) in the user data directory, suitable for complete migration or recovery, the paths are the Default folders under Windows, macOS and Linux systems respectively; 3. Turn on the Google Account synchronization function, automatically upload history to the cloud, suitable for long-term use but need to pay attention to privacy issues.
The Chrome browser itself does not have a button to directly export history, but in fact, the backup can be completed in a few simple steps. The core idea is: use Chrome's history export function, or use local files and user configuration files to implement it.

1. Export history using Chrome built-in (suitable for temporary backups)
If you just want to save a browsing history, such as the list of websites you have visited in recent days, you can use the "Export History" function that comes with Chrome:

- Open Chrome and click on the three dots in the upper right corner → "History" → "History"
- Click "Export History" next to "Clear Browsing Data" at the top of the page
- After selecting options such as time range, whether to include cookies, etc., click "Export"
- The file will be saved to your computer in HTML or CSV format
This method is simple to operate, but can only export basic information such as URL and access time , and cannot restore bookmarks or login status.
2. Copy the user data directory (suitable for full migration or recovery)
If you want to migrate history to another computer along with extensions, passwords, settings, etc., the most effective way is to copy Chrome's user data directory:

- The default path is:
- Windows:
C:\Users\用戶名\AppData\Local\Google\Chrome\User Data\Default
- macOS:
~/Library/Application Support/Google/Chrome/Default
- Linux:
~/.config/google-chrome/Default
- Windows:
In this directory, History
is a SQLite database file that contains the complete browsing history. You can copy this file, open it with SQLite tool, or directly replace it to the corresponding location on the new device.
?? Notes:
- It is recommended to turn off Chrome before operation
- Do not copy the database file you are using directly, as it may be corrupted
- You can use tools such as
sqlite3
command line to view the content of History file
3. Automatic backup using synchronization function (suitable for long-term use)
If you enable the Google Account Sync function, Chrome will automatically upload history to the cloud:
- Go to Settings → Privacy & Security → Sync
- Make sure the History item is on
- After logging in to other devices, you can automatically synchronize by simply logging in with the same account
The advantage of this approach is that it does not require manual operations and is updated in real time , but the disadvantage is that it may be uneasy for privacy-sensitive people.
Basically that's it. You can choose the appropriate method according to your needs: export function for temporary viewing, copy data directory for moving and changing to computers, and synchronous function for daily maintenance.

Chrome's incognito browsing history cannot be viewed directly, but it can be obtained indirectly through three methods. 1.
