Sitemap Index Builder
Combine multiple child sitemaps into a valid sitemap index XML file.
Group large sitemap files cleanly
Sites with many URLs often split sitemaps into separate files for pages, posts, products, images, or language sections. A sitemap index is the parent file that points crawlers to each child sitemap.
A sitemap index wraps multiple child sitemap URLs in a single sitemapindex file, which you need once a site exceeds the 50,000-URL or 50 MB limit of one sitemap.
This builder formats your child sitemap URLs into the proper sitemapindex XML structure and applies a shared lastmod date when you want a consistent timestamp.
Private browser processing
The tool does not fetch or validate the child files. It formats your pasted list locally so you can upload or review the result.
