Overview
About URL Encoder Decoder
URL Encoder Decoder uses the browser `encodeURIComponent` and `decodeURIComponent` functions to transform one URL component at a time. Use it for a query value, path segment or API parameter that needs percent encoding, not for rebuilding an entire URL without review. For example, `summer sale & offers` becomes `summer%20sale%20%26%20offers`. Decode mode reports malformed percent sequences rather than silently returning partial text. The tool does not apply form-style plus encoding, validate destinations or detect double encoding. Processing remains in the browser.
