Web URL Percent-Encoding & Decoding
RFC 3986 dictates that unreserved URI characters must be percent-encoded to prevent ambiguous HTTP request parsing. Use this tool to safely encode URI query components or decode obfuscated parameters in seconds.
Percent-encode text strings for web links, decode URL components, and parse query parameters.
RFC 3986 dictates that unreserved URI characters must be percent-encoded to prevent ambiguous HTTP request parsing. Use this tool to safely encode URI query components or decode obfuscated parameters in seconds.
URL encoding converts reserved characters and special symbols into percent-encoded hex sequences (such as %20 for spaces) so web browsers and servers can parse query strings without ambiguity. Decoding translates these sequences back into human-readable text.
Yes. Whenever a URL containing query parameters (?key=value) is pasted, the tool automatically decomposes each parameter into an interactive key-value table below the output box.
No. All URL encoding, decoding, and parameter inspection run entirely inside your browser's local JavaScript environment. No URLs or auth tokens are ever transmitted externally.
