What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's widely used to transmit binary data across systems that only support text content. The encoding process converts three bytes of binary data into four ASCII characters, making it ideal for sending images, documents, and other binary files through text-based systems.
How Base64 Encoding Works
The encoding process follows these steps:
- Binary data is grouped into 24-bit sequences
- Each sequence is divided into four 6-bit groups
- Each 6-bit group is converted to a corresponding Base64 character
- Padding (=) is added if needed
Common Applications
Base64 encoding is essential in:
- Email attachments (MIME)
- Data URIs in web development
- API data transmission
- XML and JSON encoding
