What is Base64 encoding?

Base64 is a binary-to-text encoding scheme that converts binary data into ASCII characters using a 64-character alphabet (A-Z, a-z, 0-9, +, /). It increases data size by approximately 33% but ensures safe transmission through text-only channels.

Base64 is used when binary data needs to be transmitted through systems designed for text: email attachments (MIME), embedding images in HTML (data URLs), storing binary data in JSON/XML, and HTTP Basic Authentication headers.

Frequently Asked Questions

What is Base64?

Binary-to-text encoding using 64-character alphabet. Ensures safe transmission through text-only channels.

Why use Base64?

For email attachments, data URLs, JSON binary data, and HTTP Basic Auth headers.

Is Base64 encryption?

No — it is encoding, not encryption. Anyone can decode it. Use AES/RSA for security.
