What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode data that needs to be stored and transferred over media designed to deal with text. This encoding helps ensure that the data remains intact without modification during transport.

Base64 encoding is widely used in various applications including email via MIME, storing complex data in XML or JSON, embedding image files or other binary assets inside textual assets such as HTML and CSS files, and more.
