It encodes text for safe use in URLs using encodeURIComponent, and decodes URL-encoded text back to readable form using decodeURIComponent.
How to use it
Select Encode or Decode, paste your text, and the result appears instantly. Copy it with the Copy button.

Encoding 'hello world & friends' produces 'hello%20world%20%26%20friends'. Decoding reverses this.
