What is Base64 Decoding?
Base64 decoding is the process of converting Base64 encoded text back to its original format. Base64 is a binary-to-text encoding scheme that represents binary data in ASCII string format.
Base64 decoding is essential for working with data that has been encoded for transmission over text-based protocols. It allows you to recover the original binary data from its Base64 representation.
Our free online Base64 decoder supports real-time conversion, error handling, and direct download. It's perfect for developers, system administrators, and anyone working with encoded data.
