Common uses
- Reading the actual value of a percent-encoded query parameter
- Decoding a URL copied from browser history or a log file to see its real content
- Checking what an encoded link actually points to before visiting it
Supported formats and limitations
Accepts text, up to one file at a time.
- A malformed percent sequence (like a bare `%` not followed by two hex digits) is reported as a clear error rather than crashing or silently producing garbage.
Frequently asked questions
You'll see a clear error message rather than the tool crashing or silently returning garbled text.
Yes — decoded percent-sequences are interpreted as UTF-8, so non-English text decodes correctly.
No. Decoding happens entirely in your browser.
