How to use it
- Encode UTF-8 text as Base64. Decoding accepts standard and URL-safe Base64.
- Base64 is encoding, not encryption. It provides no protection for passwords or tokens.
- This tool handles text, not arbitrary binary files. Invalid UTF-8 bytes are rejected.
Is encoded text secret?
No. Anyone can decode it without a key.
Does it support emoji?
Yes, along with other valid Unicode text.
