Base64 is an encoding algorithm that allows you to convert any characters into a Latin alphabet with digits, pluses, and slashes. You can use it to translate Chinese characters, emoji, and even pictures into a “readable” string that can be saved or transferred.

Base64 is based on an encoding algorithm that explains how to convert data to Base64 in a few simple steps. Since this is a reversible algorithm, you can easily reverse these steps to decode Base64 into original data. I don't think I'm wrong when I say that the algorithm's simplicity was one of the reasons why Base64 became so popular, and it's now used almost everywhere.
