About Base64

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode data in contexts where only text is supported, such as email attachments or embedding images in HTML/CSS.

Encoding

Converts binary data or text to a Base64 string. This is useful for safely transmitting data through text-only channels.

Decoding

Converts a Base64 string back to its original binary data or text. The input must be valid Base64 format.
