URL Parser – Parse URL Online (Free Tool)

Free online URL Parser tool to parse and analyze URLs instantly. Extract protocol, host, port, path, query parameters, and fragment from any URL. Debug URLs and understand their components. All parsing happens locally in your browser.

Example Output

Every WHATWG URL component listed individually with per-field copy buttons.

https://example.com:8080/path/to/page?id=42#section
protocol https — host example.com — port 8080 — path /path/to/page — query ?id=42 — hash #section

What is URL Parser?

URL Parser splits a URL into its WHATWG-standard components (protocol, host, port, pathname, search, hash, plus username/password where present). Useful when debugging a tracking link, validating an OAuth redirect, or building tooling that needs to manipulate URL parts programmatically.

Why use this tool?

  • No API keys to manage and no rate limits to monitor
  • 100% free with no hidden costs or daily limits
  • Works offline after the first page load
  • No telemetry on the tokens, payloads, or code you paste in
  • Built for developer workflows: copy-friendly output, syntax-aware highlighting where useful

How to use

  1. Paste any URL (with or without scheme)
  2. Read each component split out: protocol, host, port, path, query, hash
  3. Copy any field individually, or export the full breakdown as JSON
  4. Combine with Query String Parser to dive deeper into the ?... portion

Examples

Inspect a tracking URL

https://shop.com/p/widget?utm_source=email — instantly see host, pathname, and the UTM parameters separated out.

Verify an OAuth redirect URI

Paste the redirect URI registered with your auth provider — confirm the scheme is https, host matches, and the path is exactly what you registered (no trailing slashes).

Catch encoding mistakes

A literal space in the path will fail parsing — useful sanity check before sending a generated URL anywhere.

Common use cases

  • Debugging redirect chains and tracking links
  • Verifying OAuth/SSO callback URLs before saving in admin consoles
  • Building tooling that needs to extract or rewrite URL parts
  • Teaching newcomers what each piece of a URL means

Troubleshooting

"Invalid URL" error on input that "looks fine".
WHATWG URL parsing requires a scheme. Add http:// or https:// at the front and try again.

Frequently Asked Questions

The parser extracts protocol (http/https), hostname, port number, path, query parameters, and fragment (hash) from any valid URL.
