What These URL Tools Do
This is a collection of 21 free URL tools that run entirely in your browser. No software installation, no server uploads for most tools. You paste URLs, click a button, and get results instantly.
The tools cover four main workflows: encoding and decoding URLs (percent encoding, query string handling), parsing and analyzing URLs (extracting components, checking redirects, finding duplicates), generating URLs (shorteners, UTM builders, slug generators), and checking URL safety (blacklist checker, IP lookup, Wayback Machine).
How to Use These Tools
Most tools follow the same pattern:
- Paste your URL or URL list
- Select the operation or analysis type
- Adjust settings if needed
- View results and copy or download
Most processing happens client-side using JavaScript. Your URLs stay in your browser tab. Note: Tools like redirect checker or URL expander need to make network requests.
Who Uses These Tools
Marketers build UTM tracking URLs, check social media previews, shorten links for campaigns, or analyze redirect chains.
Developers parse URLs into components, encode/decode URL parameters, extract query strings, or debug canonical issues.
SEO specialists check URL canonicalization, find duplicate URLs, analyze redirects, or verify URL structure for optimization.
Security researchers check URLs against blacklists, expand shortened URLs to see destinations, or look up IP addresses for domains.

Limitations and Gotchas
URL shorteners: Browser-based shorteners may not persist. For permanent short links, use a dedicated service.
Redirect checking: Some sites block automated requests. Results may differ from browser behavior.
Social previews: Previews use Open Graph tags. Actual rendering varies by platform and may change.
URL encoding: Different contexts (path, query, fragment) have different encoding rules. Tools use standard encoding but verify for your use case.
