What is Base64?

Base64 is a binary-to-text encoding scheme that represents binary data in ASCII string format. It's commonly used to encode binary data for transmission over text-based protocols.

URL-Safe Encoding

URL-safe Base64 uses '-' and '_' instead of '+' and '/' to ensure the encoded data can be safely used in URLs without special character encoding.

Common Uses

Base64 is used in email attachments (MIME), embedding images in HTML/CSS, storing credentials, JWT tokens, and transmitting binary data over JSON.

Privacy & Security

All encoding and decoding happens locally in your browser. Your data never leaves your device and is not transmitted to any server.
