Practical guide
How to use the url converter
The URL converter percent-encodes text for use in a URL component or decodes an encoded value for inspection. Correct encoding prevents spaces and reserved characters from being misinterpreted.
Good reasons to use it
- Prepare a query value for an HTTP request.
- Read an encoded campaign or redirect parameter.
- Diagnose double-encoding in an application URL.
A reliable workflow
- Choose encode or decode and paste only the relevant value.
- Generate the result.
- Insert it in the correct URL component and test the complete request.
How to interpret the result
Encoding rules differ by component. A full URL, path segment and query value are not always encoded identically. A decoded value can contain characters with special meaning if inserted again without encoding.
Frequently asked questions
What is double-encoding?
It occurs when an already encoded percent sign is encoded again, often turning %20 into %2520.
Should I encode an entire URL at once?
Usually encode individual components according to their context rather than treating the whole URL as one value.
