Base64 Encoder/Decoder

Simply paste your text to encode or your Base64 string to decode. Fast, private, and runs entirely in your browser.

What is Base64?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with textual data.

Common Uses

• Email Attachments: Sending images or files via email (MIME).
• Data URLs: Embedding small images directly into HTML or CSS files.
• Basic Authentication: Encoding username and password credentials in HTTP headers.

Is this secure?

Yes. This tool runs 100% in your browser. Your data is never sent to our servers, so you can safely encode/decode sensitive strings (though remember, Base64 is encoding, not encryption!).
