Jan 17, 2011 · Base64 encodes each set of three bytes into four bytes. In addition the output is padded to always be a multiple of four. This means that the size of the base-64 representation of a string of size n is: ceil(n / 3) * 4 So, for a 16kB array, the base-64 representation will be ceil(16*1024/3)*4 = 21848 bytes long ~= 21.8kB.
Base64. In computer programming, Base64 is a group of binary-to-text encoding schemes that transforms binary data into a sequence of printable characters, limited to a set of 64 unique characters. More specifically, the source binary data is taken 6 bits at a time, then this group of 6 bits is mapped to one of 64 unique characters.
Nov 28, 2023 · So you need base64 when: Incompatible data is transmitted through the network. First of all it's a problem of emails – for example, encoding is necessary when you need to attach an image to a textual message. This was the reason why base64 was first introduced. Incompatible data is stored in files or elsewhere.
Jan 30, 2019 · To send three bytes of information (3 times 8 is 24 bits), you need to use four bytes (4 times 6 is again 24 bits). There might be some overhead because we often separate the base64 text into lines. Thus the base64 version of a file is at least 4/3 larger than the the original: we use at least 33% more storage than the original file size when ...
Aug 26, 2024 · Base64. Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by transforming it into a radix-64 representation. The term Base64 originates from a specific MIME content transfer encoding. When the term "Base64" is used on its own to refer to a specific algorithm, it typically refers to ...

The Base64 algorithm is a widely used encoding method for the aim of transforming binary data into a human-readable format. It works by converting binary data into a set of 64 unique ASCII characters, which are made up of upper- and lowercase letters, numerals, and a few unique symbols. Base64 is useful for a variety of tasks, including ...
