Base64 Decoding Logic

$$\text{Decoded Output} = \text{Base64}^{-1}(\text{encoded\_string})$$

The Base64 string is decoded by reversing the encoding process, transforming it into its original ASCII, binary, or textual representation.
Example:

• SGVsbG8gd29ybGQ= → Hello world

Base64 is a common encoding method used to transmit binary data in text format. This Base64 Decoder allows you to instantly decode such strings back into readable data or raw binary. It’s useful for debugging API payloads, viewing encoded email content, or decoding web data. The tool supports UTF-8 and handles common Base64 variants automatically.
