URL Master Domain Extraction Tool

Introduction to the Tool for Extracting Primary Domains from URLs:

1. This tool can extract the primary domain from a URL, supports batch extraction, and allows you to download the results to your local device.

2. This tool supports extracting primary domains from two-level or multi-level domain names, such as .com.cn, .com.au, and similar domains.

3. First, enter the URLs from which you want to extract the main domain names. If there are multiple URLs, enter one per line.

4. Click the "Start Extraction" button, and the tool will process the URLs in batches and display the extracted primary domains.

5. Click the "Copy" button to copy the extracted results, or click the "Export to TXT" button to save the results as a TXT file and download it to your local device.

6. This tool processes data entirely within your browser and does not upload your data to any server, so you can use it with confidence and peace of mind.
