About Base64
Base64 is an encoding scheme that converts binary data into ASCII text format using 64 different characters (A-Z, a-z, 0-9, +, /).
It's commonly used to encode data in URLs, emails, and data URIs. Base64 encoding increases data size by approximately 33%.
Common uses:
- Embedding images in HTML/CSS (data URIs)
- Encoding authentication credentials
- Transferring binary data over text-based protocols
- Storing complex data in JSON or XML
