XML Sitemap Generator — Free, Instant

A sitemap does not make Google rank a page, but it tells the crawler which addresses exist, and on a new or rarely linked site that decides how quickly they are found. The file itself is simple XML. The trouble is the details: an unescaped & in a query string breaks the whole file, a stray link to another domain gets ignored, and the same page listed twice wastes the crawler's time.

Paste your page addresses, one per line, or paste the HTML of a page that links to them, such as your navigation or footer, and every <a href> is used. Paths like /about are resolved against the base URL. Duplicates and #fragments are removed, other hosts and mailto: links are left out with a reason, and the result is a sitemap you can download or copy. The tool runs in your browser and cannot crawl a site, so the list you give it is the list you get.

Worked Example: A Bakery Site with Nine Lines

The page opens with nine lines for https://www.northwind-bakery.example: paths like /menu/sourdough, /menu listed twice, /menu/croissants#prices, one full address on the same site and https://instagram.com/northwindbakery. The summary reads “7 URLs in the sitemap · 1 duplicate removed · 1 #fragment dropped · 1 left out”, and the left-out entry says “different host (instagram.com); a sitemap lists one host's pages”. Below the XML is the line to add to robots.txt: Sitemap: https://www.northwind-bakery.example/sitemap.xml.

Press Load Sample for a pasted navigation menu, where a gallery?year=2026&medium=stoneware link comes out correctly escaped as &. Press it again for a shop whose /products/regnjakke-blå path is written as regnjakke-bl%C3%A5, the percent-encoded form sitemaps require.

Format Notes: What Goes in the File

• Schema: sitemaps.org 0.9, UTF-8. Output was validated against the official sitemap.xsd and siteindex.xsd while the tool was built.
• One file holds up to 50,000 URLs and 50 MB. Past either limit the list is split into sitemap-1.xml, sitemap-2.xml and so on, plus sitemap-index.xml, which is the one you submit. 60,001 URLs become two sitemaps of 50,000 and 10,001.
• lastmod, changefreq, priority are optional and apply to every URL. Google uses lastmod when it is accurate and ignores the other two, so leaving them out is fine.
• A URL must be under 2,048 characters, and an empty list is refused with “No valid URLs left to put in a sitemap.”, because a sitemap with no URLs is invalid XML for the schema.

Limits of a Paste-In Sitemap

• No crawling: a web page cannot fetch another site's pages, so pages you do not list or link to are not included. A site with a CMS usually has a plugin that keeps a sitemap up to date for you.
• One date for all: the last-modified option applies to every URL. If pages changed on different days, leave it out rather than claim a date that is not true.
• No image, video or news extensions: the file is a plain URL sitemap.
• The base URL must be a full address; www.example.com returns “Base URL "www.example.com" is not a full address. Start it with https://, e.g. https://www.example.com.”
