The Base64 tool lets you encode any text to Base64 (widely used to pass data as text in APIs, URLs or email) or decode a Base64 string back to its original text. Everything happens entirely in your browser: your content is never sent to any server. Accents and emojis are supported thanks to UTF-8 encoding. Use it as many times as you need: it is completely free, requires no sign-up and works directly in your browser.
Frequently asked questions
¿Qué es Base64?
Es un sistema que representa datos binarios con 64 caracteres seguros (letras, números, + y /), de modo que puedan viajar en textos que solo admiten caracteres imprimibles, como correos, URLs o JSON.
¿Mis datos se envían a algún servidor?
No. La codificación y decodificación se hacen con JavaScript dentro de tu propio navegador, sin conexión ni envío de datos.
¿Por qué algunos caracteres como é o los emojis no se ven bien al decodificar?
Base64 puro representa bytes. Con UTF-8, la herramienta conserva esos caracteres correctamente; si la cadena proviene de otra codificación (por ejemplo ISO-8859-1), el texto podría mostrar símbolos raros.
What is Base64?
It is a system that represents binary data with 64 safe characters (letters, digits, + and /), so the data can travel in text that only allows printable characters, such as email, URLs or JSON.
Are my data sent to any server?
No. Encoding and decoding are done with JavaScript inside your own browser, with no connection or data sent anywhere.
Why do characters like é or emojis not decode correctly?
Raw Base64 represents bytes. With UTF-8, this tool preserves those characters correctly; if the string comes from another encoding (e.g. ISO-8859-1), the text may show odd symbols.
