FAQ

Is anything uploaded?

No — it runs entirely in your browser. Your text and URLs never leave your device and are never sent to a server, so the tool works offline and keeps your data private.

What is the difference between Component and Full URL?

Component encodes every reserved character, so it is right for a single value like a query parameter (it turns ? & = / into safe codes). Full URL leaves the structural characters : / ? & # alone so a whole address stays usable, only encoding spaces and other unsafe characters.

Why did decoding show an error?

Decoding needs valid percent sequences. A stray % that is not followed by two hex digits (like %zz or a lone %) is malformed, so the tool stops and asks you to check the input rather than guessing.
