Using the url encoder & decoder
Paste a parameter value and choose Encode or Decode. This tool uses encodeURIComponent and decodeURIComponent.
Real-world example
Example: hello world & more becomes hello%20world%20%26%20more.
Good to know
This is designed for query parameter values rather than entire URLs. Encoding an entire URL would escape structural slashes and punctuation.
This tool is a planning aid, not a substitute for verifying values in vendor documentation or production configurations.
