Does this tool crawl my website?

No, this tool only validates the raw XML syntax and structure you provide. It does not ping the URLs to check for 404 errors.

Is there a size limit?

Since it runs locally in your browser, the size limit depends entirely on your device's memory. Most modern browsers can easily handle sitemaps up to 50MB.
