What is URL to DOMAIN? is a free and professional tool that extracts / parses domains and subdomains from all kinds of URLs (also called 'Internet web addresses').

For whom is this tool designed?

For webmasters, online business owners, SEO (search engine optimization) professionals, web development service providers, and Internet marketers. It may be especially handy to site owners affected by a 'negative SEO attack' who use the disavow tool offered by Google and Bing. The disavow tool allows webmasters to upload a .txt file containing a list of malicious / unwanted URLs or domains that link to the affected website in order to neutralize their potential negative effects.

What kind of TLD and gTLD names does the tool use?

URLtoDOMAIN uses all ICANN domains and the majority of private domains. The database of names is regularly updated to make sure all TLD/gTLD names are valid and properly executed by the script.

What character encoding does the tool use?

All output data is encoded in UTF-8 format.

Is there a limit on the number of URLs I can submit?

As long as you don't try to paste a million of URLs into the form at once, it should work without limits :) We strongly suggest not to include more than 500K of entries at a time to avoid service interruption (it may take up to a few minutes for the script to finish execution of a large data set). If, after submitting the form, you don't see the results in a yellow-background textarea it means you tried to work on too many URLs at the same time.

Can I save the results to a plain text (.txt) or CSV file?

You surely can! The links to Open / Save the list of parsed sub/domains in a .txt or CSV format will appear on the Results page as soon as the extracting process is completed. Please note that the results will be available for download for a few hours from the submission time and after that they will be automatically and permanently removed.
