Base64 Encoder/Decoder

Encode text to Base64 or decode Base64 back to plain text. Commonly used for data encoding and transmission.

What is Base64?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode data in email attachments, data URLs, and API communications.

The encoding process converts binary data into a set of 64 ASCII characters (A-Z, a-z, 0-9, +, /), making it safe for transmission over systems that only support text content.

Example:

  • "Hello World" encoded is SGVsbG8gV29ybGQ=
