FAQ

What is Base64 used for?
It's used to embed images and files as text, in data URIs, email attachments, and simple string obfuscation.
Is Base64 encryption?
No. Base64 is an encoding that anyone can reverse — it is not encryption and should never be used for security.
Will special characters or emoji break?
No. Everything is encoded and decoded as UTF-8, so non-Latin text and emoji stay intact.
