Sitemap Index Generator — free online
When a site gets really big, one sitemap stops being enough. Search engines cap each sitemap at 50,000 URLs or 50 MB, and past that you need a sitemap index — a small file that simply lists all your sitemaps. Building that by hand is fiddly and easy to get wrong. We added a free tool that does it for you — Sitemap Index Generator — right in your browser.
What it does
You paste in the addresses of your individual sitemaps, and it gives you back a proper sitemap index file. It follows the standard format search engines expect, so the result is valid and ready to hand over.
Nothing leaves your device
The whole thing runs in your browser. The sitemap URLs you paste are not uploaded anywhere, nothing is saved on our side, and we never see your list. It all happens on your own machine.
How to use it
- Open Sitemap Index Generator and paste your individual sitemap URLs, one per line.
- Let it build the sitemap index.
- Download the file and add it to your site.
It's free with no limit. There are more small tools on the Apps page.
