How It Works

The Sitemap Checker runs entirely in your browser using JavaScript. Unlike other tools that send your data to a server, we process everything locally on your device. This guarantees 100% privacy and blazing fast speed.

  • No server interaction – data never leaves your device
  • Instant results since there is no network latency
  • Works offline once the page is loaded
  • Free to use with no usage limits

Frequently Asked Questions

Why validate sitemaps?
A clean sitemap speeds up discovery and avoids indexing errors caused by invalid URLs or response codes.
Can I upload sitemap index files?
Yes, just paste the contents. The checker looks at all <loc> entries regardless of type.
Does checking URLs affect SEO?
No. We use HEAD requests to simply verify status codes; search engines do not see these checks.
How large can a sitemap be?
Up to 50 MB uncompressed or 50,000 URLs per file. Split larger sitemaps into multiple sub-files.
Do I need HTTPS?
Google recommends sitemaps over HTTPS to prevent tampering. Always host the file securely.
