About Base64-Decode.Online

Base64-Decode.Online is a free web application for converting the Base64-encoded data into a human-readable format. In accordance with UNIX philosophy, this online tool is designed to do one thing only and do it well — decode from Base64 format.

Write programs that do one thing and do it well.

Currently, this tool can be used to decode from Base64 to a text only, but in the nearest future it could be used to conver the Base64-encoded data into the binary files (images, PDF documents, etc.) as well.

Basically, the Base64 decoding is the process of decoding the Base64-encoded string of «printable» ASCII characters back into a binary file (image, PDF document, etc.) or into a human-readable text format. To decode the Base64-encoded string, firstly it should be converted into the binary format.

Base64-Decode.Online is written on Python and by default uses the UTF-8 character set.

The decoder converts the Base64-encoded string into the binary using the Python’s base64_string.encode() method. Then it decodes this binary data from the Base64 format using the base64.standard_b64decode() . Finally it converts the decoded binary data back to the textual format using the string_bytes.decode() method and displays the result in the text area above.

Character set The textual data decoded from Base64 should be converted from the binary format (‘bytes’ object) to the human-readable textual format (‘str’ object) by calling the string_bytes.decode() method. By default, Base64-Decode.Online uses the UTF-8 character set. If the original textual data was encoded to Base64 using another character set, you can change it using this option. The data encoded to Base64 doesn’t contain information about the character set, so if the decoded text is not readable, you may try to select another character set.

All communications with Base64-Decode.Online are secured with SSL protocol (HTTPS). Both your browser and our servers encrypt all traffic before sending any data. We do not store or inspect the contents of the entered data or uploaded files in any way.

You don’t have to pay anything. All the features of this web application are accessible free of charge.

About Decoding From Base64

The Base64 encoding is the process of encoding the binary data into a «readable» string. It allows to encode arbitrary bytes to bytes which are known to be safe to send without getting corrupted. Thanks to it, you can convert Chinese characters, emoji and even images and PDF documents into a «readable» string, which can be saved or transferred anywhere. It is commonly used when there is a need to store or transmit the binary data over systems that are designed to deal with ASCII , e.g. email via MIME . The Base64 alphabet consists of the ASCII alphanumeric character set and a couple of symbols.

The Base64 decoding is the process of decoding the Base64-encoded string of the ASCII characters back to the original binary or the textual format.

The Base64 decoding process

The Base64 encoding scheme is described in RFC 3548. The Base64 encoding takes the original binary data and devides it into chunks of 3 bytes. A byte consists of 8 bits, so Base64 takes 24 bits in total. These 3 bytes are then converted into 4 «printable» ASCII characters from the table above.

The disadvantage is that the message encodeed using the Base64 algorithm increases its length — every 3 bytes of data are encoded to 4 ASCII characters (a ~33% increase).

The Base64-encoded value of «Harry Potter» is SGFycnkgUG90dGVy .

Base64 encoded	Character	S						G						F						y						c						n						k						g						U						G						9						0						d						G						V						y
	Index	18						6						5						50						28						39						36						32						20						6						61						50						29						6						21						50
Bits		0	1	0	0	1	0	0	0	0	1	1	0	0	0	0	1	0	1	1	1	0	0	1	0	0	1	1	1	0	0	1	0	0	1	1	1	1	0	0	1	0	0	1	0	0	0	0	0	0	1	0	1	0	0	0	0	0	1	1	0	1	1	1	1	0	1	1	1	0	1	0	0	0	1	1	1	0	1	0	0	0	1	1	0	0	1	0	1	0	1	1	1	0	0	1	0
Original	Octets	72								97								114								114								121								32								80								111								116								116								101								114
	Text (ASCII)	H								a								r								r								y																P								o								t								t								e								r

Using the Base64 encoding table, the ASCII characters S , G , F , y , c , n , k , g , U , G , 9 , 0 , d , G , V , y can be converted into the numbers: 18 , 6 , 5 , 50 , 28 , 39 , 36 , 32 , 20 , 6 , 61 , 50 , 29 , 6 , 21 50 .

These numbers can be represented in 6-bit binary format as follows:

010010 000110 000101 110010 011100 100111 100100 100000 010100 000110 111101 110100 011101 000110 010101 110010

Joined together, they constitute a binary stream of:

The Base64 decoding starts from chunking this binary stream into groupings of eight characters:

01001000 01100001 01110010 01110010 01111001 00100000 01010000 01101111 01110100 01110100 01100101 01110010

Each of these groupings translates into the numbers: 72 , 97 , 114 , 114 , 121 , 32 , 80 , 111 , 116 , 116 , 101 , 114 .

Finally, these decimal values can be converted back into the original characters using to the ASCII character table: H , a , r , r , y , , P , o , t , t , e , r .

Decode from Base64 format

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.

• 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.

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.

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.

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 «_».

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:

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. Switch to mobile version
