URL component encoder & decoder
Encode or decode one UTF-8 URL component with strict percent-escape validation. Preserve literal plus signs; no URL navigation or request execution.
Encode one URL component, such as a query parameter value or a path segment. This does not parse a full URL or form body. Spaces become %20; plus signs are literal, not spaces. Malformed escapes and invalid UTF-8 are refused. Input limit: 1 MiB.
Conversion happens locally. Input is not navigated, executed, stored automatically or sent to a server.
