Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with text. This encoding helps to ensure that the data remains intact without modification during transport.

Base64 is commonly used in:

• Email attachments (MIME)
• Embedding images in HTML or CSS
• Storing complex data in JSON or XML
• Basic authentication over HTTP
• Data URLs for web applications
• Encoding binary data for cryptographic operations

Base64 encoded strings typically:

• Contain only characters from the Base64 alphabet (A-Z, a-z, 0-9, +, /, and = for padding)
• Have a length that's a multiple of 4 (padding with = as needed)
• May start with a data URI scheme like "data:image/png;base64," for embedded files

Our tool will automatically detect and handle invalid Base64 strings with appropriate error messages.
