About 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 radix-64 representation. It is commonly used to encode data when it needs to be stored or transferred over media that are designed to deal with text. This ensures that the data remains intact without modification during transport. Base64 encoded data takes about 33% more space than the original data.
