HOW IT WORKS

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.
