About these webmaster tools

These tools cover the small, frequent jobs of running a site: helping search engines find your pages, catching broken links, keeping code lean and checking who owns a domain. Paste a URL or some code and get a result in seconds.

URL-based tools fetch only the public pages you point them at. Code and text you paste are used to build your result, not stored.

Frequently Asked Questions

Enter your homepage in the Sitemap Generator. It crawls your public pages and builds an XML sitemap you can upload and submit to Google Search Console.

The Broken Link Checker scans your pages and lists every link that returns an error such as 404, with the page it was found on.

Paste your code into Minify JS/CSS. It removes whitespace and comments so files load faster, and shows how much smaller the result is. It can also beautify minified code to make it readable again.

Enter the URL in Website Screenshot and download the image. It is handy for reports, portfolios and bug tickets.

WHOIS Lookup shows the registrar, creation and expiry dates, status and nameservers of a domain.

Paste it into the IP Location Checker to see the country, region and network the address belongs to.

The Password Generator creates random passwords with the length and characters you choose. Use a different one for every account.

Yes. Every tool is free with no registration. The password generator and text tools run in your browser, and code or URLs you send to the other tools are only used to build your result.
