What is Base64?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used for transmitting data over media that are designed to deal with text.

Common uses: Email attachments, embedding images in HTML/CSS, API authentication, and data transmission.

Security Note

Base64 is NOT encryption - it's just encoding. Anyone can decode Base64 text.

Privacy: All encoding/decoding happens in your browser. Your data is not sent to any server.
