XML Sitemap Generator

An XML sitemap is a structured list of a website's pages that helps search engines discover and crawl content more efficiently, especially on larger sites or sites with pages that aren't well linked internally. The format itself is simple XML, but hand-writing it correctly — with valid absolute URLs, properly escaped special characters, and correctly nested tags — gets tedious past a handful of pages.

This tool handles the tedious part: paste a list of URLs, one per line, and it builds a valid <url> entry for each one, automatically skipping any line that isn't a valid absolute URL (starting with http:// or https://) rather than silently including something broken. Each generated entry can then optionally be given a last-modified date, a change frequency, and a priority value.

Those three optional fields are hints, not guarantees — search engines use them as one input among many when deciding how often to recrawl a page, not as binding instructions. Still, setting a recent lastmod date on frequently updated pages and a higher priority on your most important pages is a reasonable, low-effort signal to include.

The output is valid, properly escaped XML matching the sitemaps.org schema that search engines and webmaster tools expect, ready to copy directly or download as a sitemap.xml file to upload to your site's root. Everything happens instantly in your browser — there's no limit on how many URLs you can process.
