See how to use Base64 Encoding Decoding

Base64 or quadrosexagesimal is a positional notation using a base of 64. It is the largest power-of-two base that can be represented using only printable ASCII characters. This has led to its use as transfer encoding for e-mail among other things. All well-known variants that are known by the name Base64 use the characters A-Z and 0-9 in that order for the first 62 digits but the symbols chosen for the last two digits vary considerably between different systems.  A base64 encoder can allow for the safe transfer of data across various media types, while a base64 decoder will ensure the data arrives in exactly the desired format.

You can use this base64 encoding tool to convert source text data from several code pages and encode them to a base64 string.  You can also use it as a base64 decoder, decoding base64 strings to plain text.
