Frequently Asked Questions
How does percent-decoding work?
Percent-decoding translates %xx hexadecimal escape sequences back into their original UTF-8 characters, restoring human-readable text from obfuscated URLs.
Can this tool decode plus signs (+) as spaces?
Yes. In addition to standard RFC 3986 percent-decoding, the tool handles application/x-www-form-urlencoded query strings where spaces are represented as plus signs.
Is it safe to decode URLs containing private tokens or passwords?
Yes. Decoding occurs 100% client-side in your browser JavaScript engine. No decoded URLs, query parameters, or authorization tokens are ever transmitted to external servers.
