How to use it

What is Base64?

Base64 encoding allows you to represent (binary) data using only a limited, common subset of the available characters, far more efficiently than writing a string of 1s and 0s as ASCII.

Why use Base64?

Base64 is used when binary data needs to be stored or transferred over media designed to deal with text. It ensures the data remains intact without modification during transport.
