XML Sitemap Generator
Create a valid sitemap.xml from a list of URLs, with duplicate removal and validation.
What this tool does
Converts a URL list into a sitemap that follows the sitemaps.org protocol and warns about invalid, duplicate or off-host URLs.
Who should use it
Small and static sites without automatic sitemap generation.
How it works
URLs must be absolute http(s). Duplicates are dropped, special characters are XML-escaped, a maximum of 50,000 URLs is enforced and the optional lastmod is validated as a W3C date.
How to use it
- Enter or paste urls in the form.
- Adjust the options below the main box if you need to; the defaults suit most cases. Use "Load example" to see how input should look.
- Press the run button. Processing happens instantly in your browser.
- Review the result panel, then copy or download the output if the tool offers it. Use Reset to start over.
Practical example
Three URLs produce a 3-entry <urlset>.
Understanding the results
Upload as /sitemap.xml and submit it in Search Console. Priority and changefreq are omitted because Google ignores them.
Limitations
It does not crawl your site. Only list canonical, indexable URLs that return 200, and only set lastmod to true edit dates.
Accuracy and report transparency
Results are computed in your browser from exactly what you enter. Deterministic steps (counting, parsing, encoding, validation) are verified by an automated test-suite with known answers. Where a method is a heuristic, the result panel says "estimated". No external data is used and nothing is invented.
Privacy
Your input never leaves your device for this tool. We count anonymous events (tool opened, run, copied) without storing what you typed. See the Privacy Policy.
Frequently asked questions
Do I need a sitemap?
Not strictly, but it helps Google discover pages on new, large or poorly linked sites.
Is my data sent to your server?
No. This tool runs entirely in your browser, so the text or files you enter stay on your device. We do record anonymous counts of how often each tool is opened or run (no input data) to see which tools are useful.
How accurate are the results?
Counting, parsing, encoding and validation steps are deterministic and covered by automated tests with known answers. Anything based on a heuristic is labelled "estimated" in the result panel.
Is this tool really free?
Yes. There is no account, limit or paid plan. The site is supported by advertising, which is disclosed on our Advertising Disclosure page.
