Codificar

Codifica por percentagem caracteres especiais como espaços, ampersands e parâmetros de consulta para transporte seguro de URL.

Decodificar

Converte URLs codificadas por percentagem de volta em texto legível, com feedback claro sobre sequências malformadas.

Conforme RFC 3986

Usa encodeURIComponent — o padrão para codificar componentes de URL e valores de consulta.

O que é Codificador de URL?

URL encoding (percent-encoding), defined by RFC 3986, converts characters that are not allowed in a URL into a % followed by two hexadecimal digits. Reserved characters (:, /, ?, #, [, ], @, !, $, &, ', (, ), *, +, ,, ;, =) and non-ASCII characters must be encoded when used outside their reserved purpose.

Como funciona Codificador de URL?

Each character is encoded as UTF-8 bytes, then each byte that is not an unreserved character (A-Z, a-z, 0-9, -, _, ., ~) is converted to %XX form. Spaces are encoded as %20 in paths or + in query strings (application/x-www-form-urlencoded).

Casos de uso comuns

✓Query parameters — pass special characters in URL search strings
✓OAuth callbacks — encode redirect URIs
✓REST API requests — encode path and query parameters
✓International domains — encode non-ASCII characters (IDN)

URL Encoding vs Base64

URL encoding preserves URL structure (only encoding unsafe characters) while Base64 encodes the entire input. URL encoding is reversible in-place; Base64 changes the format entirely. Use URL encoding for web addresses; use Base64 for embedding binary data in text.

Segurança e privacidade

This tool runs entirely in your browser. URL encoding does NOT provide security — it only ensures characters are transport-safe. Never use it to hide sensitive data. For secure transmission use HTTPS; for data protection use encryption.

Detalhes técnicos

Standard: RFC 3986. Unreserved: A-Z a-z 0-9 - _ . ~. Reserved: : / ? # [ ] @ ! $ & ' ( ) * + , ; =. Percent-encoded: %XX (hex). Space: %20 (path) or + (query). Non-ASCII: UTF-8 bytes each encoded as %XX. JavaScript: encodeURIComponent() encodes all except A-Z a-z 0-9 - _ . ! ~ * ' ( ).

Perguntas frequentes

What is the difference between encodeURI and encodeURIComponent?

encodeURI preserves reserved URL characters (: / ? #) for full URLs. encodeURIComponent encodes everything except A-Z a-z 0-9 - _ . ! ~ * ' ( ), for use on individual query parameters.

Why is space encoded as %20 or +?

%20 is the RFC 3986 standard for paths. + is the application/x-www-form-urlencoded convention for query strings in HTML forms. Both are valid but context-dependent.
