What is Base64?

Base64 is a group of binary-to-text encoding schemes that represent binary data in ASCII string format by translating it into a radix-64 representation. It's commonly used when there's a need to encode binary data that needs to be stored and transferred over media that are designed to deal with text.

Common use cases include:

Embedding image data directly in HTML or CSS files
Sending binary data in emails
Storing complex data in JSON format
Encoding user credentials in basic HTTP authentication
