What is Base64 Decoding?
Base64 decoding is the process of converting Base64 encoded text back into its original form. Base64 is an encoding scheme that represents binary data using a set of 64 characters (A-Z, a-z, 0-9, + and /). It's commonly used to transmit binary data over systems that only support text content.
Common uses for Base64 decoding include:
- Extracting embedded images from HTML/CSS
- Reading encoded email attachments
- Decoding API responses
- Converting encoded data URLs back to text
Note: While Base64 encoding provides a way to represent binary data as text, it is not a form of encryption and should not be used for security purposes.
