The name for this encoding originates from the base definition in mathematics - 64 characters represent the numbers in Base64. In mathematics, the basis of a system of numbers refers to how many characters represent numbers. What exactly is Base64 Encoding?īase64 encoding is a form which converts bits to ASCII characters. We'll then apply Python for Base64 encoding and decoding binary and text data.
BASE64 ENCODE ONLINE HOW TO
In this article, we will discover how Base64 encodes and decodes and how to be utilized. By encoding data, we increase the chance of it being properly processed by different systems. It is the Base64 process of encryption is employed for binary data such as video or images and is transmitted through systems specifically designed to transmit information in plain-text (ASCII) form.Įncoding Base64 lets us convert binary or text data into ASCII characters. The Base64 encoding starts from chunking this binary stream into groupings of six characters:Ġ10010 000110 000101 110010 011100 100111 100100 100000 010100 000110 111101 110100 011101 000110 010101 110010Įach of these groupings translates into the numbers: 18, 6, 5, 50, 28, 39, 36, 32, 20, 6, 61, 50, 29, 6, 21 50.įinally, these numbers can be converted into the ASCII characters using the Base64 encoding table: S, G, F, y, c, n, k, g, U, G, 9, 0, d, G, V, y.What Is Base64 Encoding? How Does Base64 Encoding And Decoding Work?īase64 encoding is the process of converting binary data into the ASCII string format, by converting the binary data into the character representation of 6-bits. The Base64-encoded value of "Harry Potter" is SGFycnkgUG90dGVy.Įncoded in ASCII, the characters H, a, r, r, y,, P, o, t, t, e, r are stored as the decimal values: 72, 97, 114, 114, 121, 32, 80, 111, 116, 116, 101, 114. 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). These 3 bytes are then converted into 4 "printable" ASCII characters from the table above. A byte consists of 8 bits, so Base64 takes 24 bits in total. The Base64 encoding takes the original binary data and devides it into chunks of 3 bytes. The Base64 encoding scheme is described in RFC 3548. The Base64 alphabet consists of the ASCII alphanumeric character set and a couple of symbols.
The Base64 encoding 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.
BASE64 ENCODE ONLINE PDF
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 allows to encode arbitrary bytes to bytes which are known to be safe to send without getting corrupted. The Base64 encoding is the process of encoding binary data into a "readable" string.

All the features of this web application are accessible free of charge. We do not store or inspect the contents of the entered data or uploaded files in any way. Both your browser and our servers encrypt all traffic before sending any data. The data encoded to Base64 doesn't contain information about the character set, so to decode it from Base64 you may have to specify the character set selected during encoding.Īll communications with Base64-Encode.Online are secured with SSL protocol (HTTPS). If you want to convert the input textual data to another character set before encoding it to Base64, you can change the character set using this option. By default, Base64-Encode.Online uses the UTF-8 character set. Finally it decodes the Base64 binary string back to the textual format using the base64_code() method and displays the result in the text area above.Īdvanced options Character set To encode textual data ('str' object) to Base64, firstly it should be converted to the binary format ('bytes' object) by calling the string.encode() method. Then it encodes this binary data to Base64 using the base64.standard_b64encode(). The encoder converts the textual data into the binary using the Python's string.encode() method. Base64-Encode.Online is written on Python and by default uses the UTF-8 character set.
