Can this decode any Base64 file?

Yes. The generic decoder accepts valid Base64 input and tries to detect the original file type automatically.

How is the file type detected?

The decoder checks data URI prefixes first, then falls back to file signature detection where possible.

What happens if the type cannot be detected?

If detection is limited, the file is still generated and returned with a generic binary extension.
