SEO tools & utilities
Paste a urlset XML and split it into 50,000-URL chunks with a sitemap-index, or paste multiple urlsets and merge them into one deduplicated file. Pure client side.
Our sitemap splitter and merger transforms sitemap XML you already have. Split mode takes one large urlset and chunks it into 50,000-URL pieces, the per-file limit that sitemaps.org enforces. The output is a ZIP containing sitemap-1.xml through sitemap-N.xml plus a sitemap-index.xml that points at them with absolute URLs. Merge mode takes two or more urlset XML inputs, combines them, removes duplicates case-insensitively, and emits one merged urlset XML.
The tool is pure client side. Both modes parse the XML you paste, never fetch a URL, and never send your data anywhere. The Splitter accepts a urlset and asks you for the public base URL where the chunk files will be hosted so the parent index points at absolute URLs (which is what Google, Bing, and Yandex require).
