What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in ASCII string format. It is commonly used to encode binary data for transmission over text-based protocols.
Base64 encoding is essential for safely transmitting binary data through systems that are designed to handle text. It ensures that binary data remains intact during transmission, regardless of the character encoding used by the system.
Our free online Base64 encoder supports real-time conversion, error handling, and direct download. It's perfect for developers, system administrators, and anyone working with binary data.
