Base64 is a binary-to-text encoding scheme that represents binary data in an 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 textual data.

Common use cases for Base64 encoding include:

• Embedding image data directly in HTML or CSS
• Sending binary data via email
• Storing complex data in JSON
• Encoding binary data to be included in URLs
