Decode & Encode with the SUDTCore Base64 Suite

**Base64** is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is commonly used to embed images in HTML/CSS (Data URIs), transmit data across media that expect text, and perform simple obfuscation for Basic Authentication headers.

How to Use

Encoder: Paste raw text to get a Base64-safe string for URLs or configurations.
Decoder: Paste an encoded string to reveal the original readable text.

Privacy Warning

While Base64 is used in headers, it is NOT encryption. Anyone can decode a Base64 string instantly. Never use it for sensitive passwords without actual encryption (like AES).
