Base64 Encode Text

What is base64 encoding?

Some tools do not accept a full set of characters. There are also text file formats that do not have a way to escape easily all special characters. Some special characters are new lines, tabs, characters that are otherwise used for other purposes - &, % etc.

Example usages:

content of cookies
some url parameters - but often url encoding is used there
contents of some kubernetes objects
encoding binary content to store as text

Example of base64 encoded text

How Base64 Encoding Works

Base64 encoding converts binary data into a text format by representing it using 64 different ASCII characters. The process works as follows:

The input text is converted to binary data (using UTF-8 encoding)
The binary data is split into groups of 6 bits (since 2^6 = 64)
Each 6-bit group is converted to a corresponding character from the Base64 alphabet
If the input length is not divisible by 3, padding characters ('=') are added to the output

Parameters

Input text: Any text you want to encode to Base64 format

Common Use Cases

Embedding binary data in JSON, XML, or HTML
Storing data in cookies or URL parameters
Email attachments (MIME encoding)
Storing configuration data in text files
Encoding data for APIs that don't support binary data

Tip:

Base64 encoding increases the size of your data by approximately 33% compared to the original binary data. This is because every 3 bytes of input data are represented as 4 bytes in Base64 format.
