Base64 Encoding and Decoding Tool

Base64 is a ASCII-text encoding. This means it can any binary data into a text string, or compress ASCII text into a text string. But other text encodings (like UTF-8 or UTF-16) can also be encoded (as they are binary data as well).

The Base64 alphabet uses 64 charaters: A-Z, a-z, 0-9, + and /. An additional character = is used for padding if necessary because of how it encodes data.
