help What is Base64?

Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format. By translating it into a radix-64 representation, Base64 ensures that the data remains intact without modification during transport.

Limitations: Base64 is an encoding mechanism, not encryption. It provides zero security or obfuscation. Additionally, Base64 encoding increases the original data size by approximately 33%.
