About URL Decode
URL decoding reverses percent-encoding: sequences like %20 become spaces and %2F becomes /.
Use it when you paste an encoded query parameter and need the original value for debugging or documentation.
Decoding is local and is not decryption—anyone can decode the same string.
How to use it
- 1Paste the encoded string.
- 2Decode to plain text.
- 3Copy the readable result.
