Meet 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.
Advanced options
- Character set: In case of textual data, the encoding scheme does not contain the character set, so you have to specify which character set was used during the encoding process. It is usually UTF-8, but can be many others; if you are not sure then play with the available options or try the auto-detect option. This information is used to convert the decoded data to our website's character set so that all letters and symbols can be displayed properly. Note that this is irrelevant for files since no web-safe conversions need to be applied to them.
- Decode each line separately: The encoded data usually consists of continuous text, so even newline characters are converted into their Base64 encoded forms. Prior to decoding, all non-encoded whitespaces are stripped from the input to safeguard the input's integrity. This option is useful if you intend to decode multiple independent data entries that are separated by line breaks.
- Live mode: When you turn on this option the entered data is decoded immediately with your browser's built-in JavaScript functions, without sending any information to our servers. Currently, this mode supports only the UTF-8 character set.

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.
