How to use the URL Decoder

Paste the encoded string.
Press Decode.
Copy the human-readable result.
Fix incomplete % sequences if decoding errors appear.

How it works

Percent sequences (%HH) are converted back to their original characters. Invalid sequences may be left unchanged or flagged depending on the implementation.

Useful when inspecting logs, campaign links and API callbacks.

Examples

hello%20world → hello world
%7B%22a%22%3A1%7D → {"a":1}
Strings without % sequences return unchanged

URL Decoder FAQ

Why is part of my string still encoded?

Double-encoding needs two decode passes. Incomplete % sequences cannot be decoded.

Does it decode “+” as space?

Behavior follows the tool’s rules—some decoders treat + as space in query strings.

Is the URL Decoder free?

Yes.
