URL Decoder – Decode Percent Encoded Text | MZ Smart Tools House
Decode percent-encoded URL components or complete URLs and report malformed % sequences.
Recover readable text from percent encoding without silently accepting malformed escape sequences.
How it works
Component mode uses decodeURIComponent semantics; full-URL mode uses decodeURI semantics.
Example
hello%20world → hello world
Frequently asked questions
What happens to hello%ZZ?
It is rejected because %ZZ is not valid percent encoding.
Does + always mean a space?
No. This tool does not silently apply form-urlencoded plus-to-space rules.
