Work starts the moment you drop a file
No daily limit, no sign-up, no watermark

Use x-default for a language selector or fallback locale, not as a junk drawer for untranslated URLs.
HTML head, HTTP headers, or sitemaps. Pick one strategy and stay consistent.
That is the promise behind every tool here. Files are read in your browser tab, processed there, and discarded when you close it — never uploaded to our servers.
Generate canonical link tag.
Build a urlset XML from a URL list with escaping, dedupe, and optional download — in your browser.
Compose robots.txt with Allow/Disallow lines, sitemap URL, and warnings for Disallow: /.
Title, description, optional Open Graph/Twitter tags — escaped HTML, no meta keywords.
Apache/nginx redirect snippets.
