What is Base64 Encoding? A Developer's Guide
Understanding Base64 encoding: how it works, common use cases, and when to use it. Perfect for developers working with APIs, email, and data URIs.
Base64 is a binary-to-text encoding scheme that's fundamental to modern web development. It converts binary data into an ASCII string format that can be safely transmitted over text-based protocols.
How Base64 Works
Base64 encoding takes binary data and represents it using 64 different ASCII characters (A-Z, a-z, 0-9, +, /). The process:
Common Use Cases
Important Security Note
Base64 is encoding, NOT encryption. Anyone can decode Base64 instantly. Never use Base64 for sensitive data like passwords or personal information.
