Free Sitemap Index Generator Tool
Our free sitemap index generator creates XML sitemap index files from multiple sitemap URLs. Perfect for large websites that need to organize multiple sitemaps into a single index file. The tool generates valid XML following the Sitemaps protocol standards, allowing you to combine sitemaps for posts, pages, products, categories, and other content types. Simply enter your sitemap URLs (one per line), and the tool instantly generates a properly formatted sitemap index XML. You can copy the XML to your clipboard or download it as a file named sitemap-index.xml. Sitemap indexes are essential for large websites exceeding the 50,000 URL or 50MB limit per sitemap. They allow search engines to efficiently discover and crawl all your content. The generated XML includes proper namespaces and structure required by Google, Bing, and other search engines. All generation happens locally in your browser with no server processing or data storage.
