Base64 Encoder/Decoder

Encode and decode text using Base64 encoding. Essential for data transmission, email attachments, and web development.

What is Base64?

Base64 is a binary-to-text encoding scheme that represents binary data in ASCII format using 64 printable characters (A-Z, a-z, 0-9, +, /).

Common Applications:

• • Email attachment encoding (MIME)
• • Embedding images in HTML/CSS
• • API authentication tokens
• • URL-safe data transmission
• • Database storage of binary data

Important Notes:

• • Base64 is encoding, not encryption
• • Increases data size by ~33%
• • Safe for text-based protocols
