What Is Base64 Encoding and Why Does It Matter?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used in email via MIME, storing complex data in XML or JSON, and embedding images directly into HTML or CSS.

How Base64 Works

Base64 encoding takes binary data and converts it into a set of 64 characters: A–Z, a–z, 0–9, +, and /. This makes it safe to transmit over systems that are designed to handle textual data.

For example, the word "hello" in Base64 becomes aGVsbG8=.

Benefits of Using Base64

Safe Transmission: Ensures binary data can be sent over text-based protocols.

Compact Format: Encoded data is more compact than hexadecimal.

Universal Support: Widely supported across programming languages and platforms.
