What is URL encoding?

URL encoding, also called percent encoding, represents characters using a percent sign followed by hexadecimal digits. It is useful when passing values containing spaces or reserved characters in URLs.

When should you use it?

  • Encoding query parameter values in API requests.
  • Decoding percent-encoded text when debugging URLs.
  • Preparing search terms containing spaces or symbols.
  • Inspecting values passed between web applications.

Example

Original text

hello world & React

Encoded text

hello%20world%20%26%20React

This tool uses the browser's encodeURIComponent and decodeURIComponent functions. Encoding is applied to a component or text value, not to an entire URL with its structural separators.
