What is Base64?

Base64 is a robust encoding scheme used to represent binary data in an ASCII string format. It is commonly used when there is a need to encode binary data that needs to be stored or transferred over media that are designed to deal with text.

Common Use Cases

• Data Transmission: Sending binary data (like images) in JSON APIs.
• Email Attachments: MIME uses Base64 to encode files.
• Data URLs: Embedding small images directly into HTML/CSS files using data:image/png;base64,....
