What is Base64?

Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a base-64 representation. The term Base64 comes from the specific MIME content transfer encoding.

This tool is useful if you need to transmit data that contains characters incompatible with your system.

For example, if you need to send an image or file via email or through a web server, but your system does not support certain characters, you can use Base64 to encode that data into an ASCII string that can be transmitted without issues.

Base64 is also used for encoding passwords and other sensitive data, as the resulting ASCII string can be transmitted safely over a network.

Base64 encoding works as follows: every three bytes of data are converted into four ASCII characters, each representing six bits. If the number of bytes is not divisible by three, additional characters are used for padding.

For example, the string "Hello, world!" in Base64 looks like: "SGVsbG8sIHdvcmxkIQ==". This means that each character in the string was converted into its hexadecimal value, then combined with other values and converted into an ASCII character.

Base64 is a standard supported by most programming languages and operating systems.
