Base64 Encode Decode

Base64 Encode/Decode




Base64 Decode and Encode, a simple online tool that does exactly what it says: decodes from Base64 encoding as well as encodes into it quickly and easily. Base64 encode your data without hassles or decode it into a human-readable format.

Base64 encoding schemes are commonly used when there is a need to encode binary data, especially when that data needs to be stored and transferred over media that are designed to deal with text. This encoding helps to ensure that the data remains intact without modification during transport. Base64 is used commonly in a number of applications including email via MIME, as well as storing complex data in XML or JSON.

Details of the Base64 encoding

Base64 is a generic term for a number of similar encoding schemes that encode binary data by treating it numerically and translating it into a base-64 representation. The Base64 term originates from a specific MIME-content transfer encoding.


Here's a quote snippet from Thomas Hobbes's Leviathan:

"Man is distinguished, not only by his reason, but ..."

This is represented as an ASCII byte sequence and encoded in MIME's Base64 scheme as follows:
