Upload or paste a URL sitemap. The splitter keeps every child file below your URL count and Google's 50 MB uncompressed limit.
Your sitemap stays in this browser. The tool keeps loc, lastmod, changefreq, and priority values, then starts a new file before either the URL or 50 MB uncompressed limit is crossed.
A single sitemap can contain at most 50,000 URLs and must stay below 50 MB uncompressed. This tool checks both limits while it builds each part, then creates an index that points to their public locations. It does not claim that smaller files improve rankings; splitting is required only when a file crosses a protocol limit or when separate sections make monitoring easier.
Standard loc, lastmod, changefreq, and priority fields are retained. Image, video, news, and other extension elements are not copied, so use a format-specific splitter when those elements matter.
The splitter accepts a URL sitemap, not a sitemap index. Use the sitemap crawler to map an existing index, or the sitemap checker to validate each live file after uploading it.
