Complete guide to using the URL Encode/Decode tool

URL Encoding represents special meaning or unsafe bytes in a URL as a sequence of percentages. The allowed characters for full URLs, path fragments, and query parameters are different, and the corresponding APIs should be used instead of re-encoding the entire URL.

Operation steps

  1. Determines whether to process a full URL, a path, or a single parameter value
  2. Enter the original text and execute Encode or Decode
  3. Check whether %, +, &, = and Unicode characters comply with receiver rules

Practical suggestions and limitations

In JavaScript, encodeURIComponent is suitable for a single parameter value, while URL and URLSearchParams are more suitable for combining complete URLs. Handle format errors when decoding unknown input.

Privacy and native processing

The URL and parameters are only converted in the browser and will not be sent to the target website.
