Parse and edit URLs and query strings, generate UTM links, slugs, meta tags, robots.txt, and sitemaps, and preview social sharing cards. Output is escaped and ready to paste.
Nothing is crawled or fetched; every preview is composed from the values you provide.
Links and URLs
The URL parser breaks an address into protocol, host, path, query parameters, and fragment, and resolves relative links against a base. The query string editor lets you edit parameters as rows, including repeated names, and rebuilds a correctly encoded URL. The UTM builder adds consistent campaign parameters for analytics, and the slug generator turns a title into a clean, readable URL path.
Correct encoding is the recurring theme: spaces, ampersands, and non-ASCII characters in a URL must be encoded exactly once. These tools use the same URL rules as browsers, so what you see is what a browser will request.
Search and sharing metadata
The meta tag generator writes title, description, canonical, and robots tags with a search-result preview. The social card preview produces Open Graph tags for rich link previews on Facebook, LinkedIn, Slack, and messaging apps. The robots.txt generator builds crawl rules, and the sitemap generator produces an XML sitemap for a small site.
Metadata helps search engines and social platforms understand a page, but it does not guarantee rankings or display. Search engines may rewrite titles, and platforms cache previews. The guides explain what each file and tag actually controls, and what it does not.
