What is Base64 Encoding?
Base64 encoding is a process of converting binary data into an ASCII string format. It uses 64 unique characters (A-Z, a-z, 0-9, +, and /) to represent data, making it safe to transmit over text-based protocols like HTML, CSS, and JSON.
Why use Base64?
- ✅ **Data Embedding**: Embed images directly in CSS or HTML as Data URLs.
- ✅ **Safe Transmission**: Send binary data over protocols that only support text.
- ✅ **Data Integrity**: Prevent characters from being misinterpreted during transit.
