Base 64 Encoding, Decoding Tool

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 a transfer encoding for e-mail among other things. All well-known variants that are known by the name Base64 use the characters A–Z, 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.

You can use this base64 encoder and decoder to convert source text data from several code pages and encode them to a base64 string or decode base64 strings to a plain text.
