About Base64 Encoding
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 binary data needs to be stored or transferred over media that are designed to deal with text.
Common use cases for Base64 encoding include:
- Embedding binary data in JSON or XML
- Encoding images for embedding directly in HTML or CSS
- Sending binary data in email attachments
- Storing complex data in cookies or local storage
- Transmitting data in URLs where binary data might be problematic
Note that Base64 encoding increases the data size by approximately 33% (a ratio of about 1.33x) because it represents 3 bytes of data with 4 ASCII characters.
