ABOUT

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.

Safe and secure

All communications with our servers come through secure SSL encrypted
connections (https). We delete uploaded files from our servers immediately after
being processed and the resulting downloadable file is deleted right after the
first download attempt or 15 minutes of inactivity (whichever is shorter). We do
not keep or inspect the contents of the submitted data or uploaded files in any
way. Read our privacy policy below for more details.

Completely free

Our tool is free to use. From now on, you don't need to download any software
for such simple tasks.

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.

Design

The particular choice of characters to make up the 64 characters required for
Base64 varies between implementations. The general rule is to choose a set of 64
characters that is both 1) part of a subset common to most encodings, and 2)
also printable. This combination leaves the data unlikely to be modified in
transit through systems such as email, which were traditionally not 8-bit clean.
For example, MIME's Base64 implementation uses A-Z, a-z, and 0-9 for the first
62 values, as well as "+" and "/" for the last two. Other variations, usually
derived from Base64, share this property but differ in the symbols chosen for
the last two values; an example is the URL and filename safe "RFC 4648 /
Base64URL" variant, which uses "-" and "_".

Example

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:

TWFuIGlzIGRpc3Rpbmd1aXNoZWQsIG5vdCBvbmx5IGJ5IGhpcyByZWFzb24sIGJ1dCAuLi4=

In the above quote the encoded value of Man is TWFu. Encoded in ASCII, the
letters "M", "a", and "n" are stored as the bytes 77, 97, 110, which are
equivalent to "01001101", "01100001", and "01101110" in base-2. These three
bytes are joined together in a 24 bit buffer producing the binary sequence
"010011010110000101101110". Packs of 6 bits (6 bits have a maximum of 64
different binary values) are converted into 4 numbers (24 = 4 * 6 bits) which
are then converted to their corresponding values in Base64.



Text content M a n ASCII 77 97 110 Bit pattern 0 1 0 0 1 1 0 1 0 1 1 0 0 0 0 1 0
1 1 0 1 1 1 0 Index 19 22 5 46 Base64-encoded T W F u


As this example illustrates, Base64 encoding converts 3 uncoded bytes (in this
case, ASCII characters) into 4 encoded ASCII characters.
