XML Sitemap Generator Online (100% Free & Private)
Free xml sitemap generator that runs in your browser. No sign-up, no install.
XML Sitemap Generator
Paste URLs, one per line. Add per-URL values with pipes: url | lastmod | changefreq | priority. Every value is XML-escaped.
Escaped characters: & < > ' and " are converted to XML entities in every field (&, <).
What this tool does and who it is for
Paste a list of absolute URLs and get a valid sitemap.xml. For per-URL details, add pipes: url | lastmod | changefreq | priority. Every value is XML-escaped, so ampersands and quotes in URLs do not break the file.
Lastmod is blank unless you provide it, because a wrong date is worse than none. A single sitemap holds up to 50,000 URLs, so larger lists are split into several files with a sitemap index.
