Enter values, then process to see the result.

How to use it

  1. Choose encode or decode.
  2. Enter one component value.
  3. Process and copy the reviewed output.

Important limitation

Treats all input as one component. Parse complete URLs and encode their individual values instead of encoding a whole URL blindly.
