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.
