Free Online Sitemap Generator
A free online sitemap generator that runs entirely in your browser. Paste your page URLs (or the HTML of a page to pull its links) and instantly build a valid XML sitemap, a matching HTML sitemap, and a robots.txt snippet — no sign-up required.
Generate your sitemap
Paste your page URLs (or extract them from a page), set options, and download sitemap.xml, an HTML sitemap, and robots.txt.
Your sitemap.xml will appear here as you add URLs.
How to generate a sitemap online for free
Add your URLs
Paste your page URLs one per line, or paste a page's HTML and let the tool extract the links for you. You supply the addresses — nothing is fetched from a server.
Set your options
Choose a lastmod date, change frequency, and priority for your pages, or let auto-priority assign values based on each URL's depth in the path.
Copy or download
Generate a valid sitemap.xml, an HTML sitemap page, and a robots.txt snippet. Copy each one or download the files, then upload them to your site root and submit the sitemap in Search Console.
Why an accurate XML sitemap matters
An XML sitemap follows the sitemaps.org protocol and lists the URLs you want search engines to know about, along with optional lastmod, changefreq, and priority hints. It does not guarantee indexing, but it helps crawlers discover pages on new sites, large sites, or pages with few internal links — and once submitted to Google Search Console or Bing Webmaster Tools, it gives you coverage reporting on what was found.
Tip: keep a single sitemap under 50,000 URLs and 50 MB uncompressed, use absolute https URLs, and reference the file in your robots.txt with a Sitemap line so crawlers can find it on their own. Pair the XML file with the generated HTML sitemap to give human visitors a clean, linkable index of your site. Because browsers cannot read other domains directly (CORS), this tool builds from the URL list you provide rather than crawling a live site for you.
Frequently asked questions
Does this sitemap generator crawl my website automatically?
No. Browsers cannot fetch pages from other domains because of CORS, so this tool does not spider your site from a server. You provide the URLs — either by pasting a list (one per line) or by pasting a page's HTML so the tool can extract the links it contains. That keeps everything 100% in your browser with no upload.
Is the XML sitemap it produces valid for Google Search Console?
Yes. The output follows the standard sitemaps.org XML schema with
What is the difference between the XML sitemap and the HTML sitemap it creates?
The XML sitemap is a machine-readable file for search engine crawlers. The HTML sitemap is a human-readable page of links you can publish on your site so visitors (and crawlers following internal links) can navigate your pages. The tool builds both from the same URL list in one step.
What does the auto-priority by URL depth option do?
Instead of setting a priority for every page by hand, auto-priority assigns higher priority values to URLs closer to the root and lower values to deeper, more nested paths. Priority is only a relative hint for crawlers within your own site and does not affect rankings, but it is a fast way to fill the field sensibly.
Do I need to sign up or install anything?
No. There is no sign-up, no account, and no software to install. The generator runs in your browser, your URLs never leave your device, and you can copy or download the sitemap.xml, HTML sitemap, and robots.txt snippet for free.
