HTML Sitemap Generator, Build a Nested Sitemap Page Online
Paste your URLs and get a clean, nested HTML sitemap, a linkable list grouped by folder that you can drop into any page. Great for navigation, internal linking and helping users (and crawlers) reach every page. Generated entirely in your browser: no crawl, no upload, no signup.
What is the html sitemap generator?
The HTML Sitemap Generator turns a pasted list of URLs into a nested, linkable sitemap page, grouping links by folder path so /blog/2026/post nests under /blog. Export the semantic UL fragment or a complete styled sitemap.html to boost navigation and internal linking. Free and browser-based, with no crawl and nothing uploaded.
The GigAI HTML Sitemap Generator turns a plain list of page URLs (one per line, pasted or dropped from a.txt file) into a human-readable sitemap page: a nested <ul> that mirrors your site's folder structure, with every page as a real anchor link. Unlike an XML sitemap, which is a machine file for search engines, an HTML sitemap is a page your visitors actually see: it gives people a single index of your whole site, surfaces deep or 'orphan' pages that aren't linked from the main navigation, and hands search engines a dense block of crawlable internal links from one authoritative page. As you type, URLs are grouped by their path segments so /blog/2026/post nests neatly under /blog, and XML/HTML special characters in your URLs are escaped so the markup is always well-formed. Choose whether to emit just the semantic <ul> fragment (to paste inside your own template) or a complete, styled standalone HTML page you can save and publish as sitemap.html. When it looks right, copy the markup, download the file, or preview the rendered tree live. Because everything runs 100% in your browser from the URLs you already have, there is no page limit we impose, nothing is uploaded, and your staging or unpublished URLs never leave your machine.

How to use the html sitemap generator
- 1
Paste your URLs
Enter one absolute URL per line, or drop a .txt file. Lines starting with # are ignored, so you can annotate or comment out URLs.
- 2
Choose fragment or full page
Pick 'Fragment' to get just the <ul> to embed in your own template, or 'Full HTML page' for a complete, lightly-styled sitemap.html you can publish as-is.
- 3
Preview the rendered tree
Check the live preview to confirm the nesting and link labels look right, then tweak your URL list until the structure matches your site.
- 4
Copy or download
Copy the markup into your page template, or download the .html file. Link to it from your footer so both users and crawlers can find it.
What HTML Sitemap Generator includes
URL list → nested link tree
Paste one URL per line and get a semantic <ul>/<li> tree that mirrors your folder structure, with each page rendered as a real, clickable anchor link.
Automatic path grouping
URLs are grouped by their path segments, so /blog/2026/guide nests under /blog under the root. No manual indentation or ordering required.
Fragment or full page
Emit just the semantic <ul> to paste inside your own template, or a complete styled standalone HTML document you can publish as sitemap.html.
Live rendered preview
See the actual clickable, indented sitemap as it will appear on your page, alongside the raw markup. No guessing how the list nests.
Internal-linking boost
One HTML sitemap gives search engines a dense hub of crawlable links to every page, helping deep and orphan pages get discovered and indexed.
100% in your browser
No crawler, no server, no page cap. Your URLs, including staging and unpublished pages, are turned into markup locally and never uploaded or logged.
Why use our html sitemap generator
Help visitors find any page
A single indexed list of every URL gives people a fast way to reach deep pages that the main navigation doesn't expose, reducing dead ends and bounce.
Strengthen internal linking
Search engines follow the links on an HTML sitemap, so one page can pass crawl signals to your entire site and surface pages that are otherwise orphaned.
Ship accessible, semantic markup
The output is a plain nested <ul> of anchors: screen-reader friendly, keyboard-navigable, and easy to style to match your brand.
Keep unpublished URLs private
Nothing is crawled or uploaded, so you can build a sitemap page from staging or pre-launch URLs without exposing them to a third-party server.

Common problems, solved
Hit a snag? Here are quick fixes for the issues people run into most.
My link labels are just slugs like 'guide' instead of nice titles.
Labels are derived from each URL's last path segment, because the tool only knows the URLs you paste. It can't fetch page titles (that needs a server we don't run). Publish the fragment, then edit the anchor text in your template, or rename your slugs to be more descriptive.
The nesting isn't grouped the way I expected.
Grouping follows the URL path, not your visual menu. /blog/post nests under /blog. If two pages should sit together, make sure their URLs share a common path prefix. Query strings and hashes don't affect nesting.
Should this replace my XML sitemap?
No. They serve different jobs. Keep the XML sitemap for Search Console submission and crawl hints, and add the HTML sitemap as a real page for users and internal linking. Use both together for the best coverage.
Get the most out of it
Link to your HTML sitemap from the footer on every page. That single internal link is how both users and crawlers discover it.
List only canonical, indexable URLs. Leave out noindex, redirected and duplicate pages so the page sends clean signals.
Use descriptive slugs, because labels come from the last path segment, /pricing reads better than /p?id=42.
Keep an XML sitemap as well: the HTML page is for humans and internal links, the XML file is for Search Console.
For very large sites, split the sitemap page by section (one per top-level folder) so each stays scannable.
