![]() 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. 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. ![]()
