Common questions
Does Base64 keep text secret?
No. Base64 is reversible encoding, not encryption or security.
Can I decode images or URL-safe Base64?
This release handles standard padded Base64 containing UTF-8 text. Binary files and URL-safe -/_ variants are not supported. Invalid padding and invalid UTF-8 show an error.
