What is Base64 Encoding?
How Base64 Works
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It converts every 3 bytes of binary data into 4 characters of Base64 text.
- Converts binary data to ASCII text
- Uses 64-character alphabet (A-Z, a-z, 0-9, +, /)
- Adds padding characters (=) when needed
- Increases data size by approximately 33%
Common Uses
Base64 encoding is widely used for embedding binary data in text-based formats, transmitting files through text protocols, and storing binary data in databases.
- Embedding images in HTML/CSS
- Email attachments and MIME
- HTTP Basic Authentication
- JSON/XML binary data storage
