How it works
- Paste one URL per line.
- Set the default change frequency, priority and last-modified date.
- Download sitemap.xml and reference it from robots.txt.
Why nothing is uploaded
Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.
Verify it yourself
- Open your browser’s developer tools (F12) and select the Network tab.
- Load your file and run the tool.
- The only requests you will see are the tool’s own code and, once cached, none at all.
Frequently asked questions
Do changefreq and priority do anything?
Very little. Google has said for years that it largely ignores both; lastmod is the field it does use, and only when it is accurate. An honest lastmod beats a page of invented priorities.
How many URLs fit in one sitemap?
50,000 URLs or 50 MB uncompressed, whichever comes first. Beyond that you split it and add a sitemap index. The tool warns you at the limit instead of producing a file that will be rejected.
Does anything leave my browser?
No. There is no server behind this page doing the work and no API being called — the whole tool is JavaScript running in the tab. Load it once and it keeps working with the connection off.
