Input & Mode
What is URL Encoding?

URL encoding converts characters into a format that can be transmitted over the Internet. URLs can only be sent over the Internet using the ASCII character-set.

  • Space: Becomes %20
  • Special Chars: !, #, $, %, & are replaced by hex codes.
  • Safety: Ensures that query parameters don't break the actual URL structure.

How to use the URL Encoder Decoder

Developers frequently need to manually encode strings to pass them into GET parameters or API endpoints. This tool provides a clean, private interface to do exactly that.

Encoding

Switch to Encode Mode to transform characters like spaces or emojis into valid URL percent-encoding (e.g., %20).

Decoding

Switch to Decode Mode if you have a messy URL and want to see the actual plain-text values inside the query string or path.
