What is the URL Parser?
Break a URL into protocol, host, path, query parameters and fragment. Breaking a URL into its parts — protocol, host, path, query parameters and fragment — makes complex links easy to inspect and debug.
How to use the URL Parser
- Paste or type your your text into the box (a sample is pre-filled so you can see how it works).
- Results update automatically as you type; you can also press Calculate.
- Read the output: result.
- Use the 📊 chart to see the result visually, then copy or share it.
Where the URL Parser helps in real life
A marketing team wants to check which UTM tags a long campaign link carries. Parsing it lists each parameter and value separately.
A developer debugging a redirect loop parses each URL in the chain to see which parameter changes.
Common mistakes to avoid
- Overlooking a lookalike domain hidden in a long link.
- Confusing the path with query parameters.
- Missing parameters that appear twice.
- Assuming the fragment is sent to the server.
💡 Practical tip: The part after # is never sent to the server, so it cannot be seen in server logs.
Tips for better results
- Check the host carefully for misspellings.
- Look for duplicate parameter names.
- Remember that everything after # stays in the browser.
