About the Base64 Encoder & Decoder

Base64 is a text encoding scheme that represents binary or plain text data using only 64 safe printable characters (A-Z, a-z, 0-9, + and /). It's widely used to safely embed data in places that only accept plain text, like email attachments, URLs and JSON payloads.

How it works: Encoding groups the input's raw bytes into 6-bit chunks and maps each chunk to one of 64 characters from the Base64 alphabet; decoding reverses this process to recover the original bytes.

Base64 is an encoding, not an encryption — anyone can decode it instantly, so it should never be used to protect sensitive information, only to safely transport data through text-only channels.
