Frequently Asked Questions

What is Base64?

Base64 is a binary-to-text encoding scheme that represents binary data using 64 ASCII characters (A–Z, a–z, 0–9, +, /). It is commonly used to encode data in email, web APIs, and data URLs.

Does it support Unicode?

Yes. The encoder uses UTF-8 encoding under the hood via encodeURIComponent, so multi-byte Unicode characters (emoji, CJK, Arabic, etc.) are handled correctly.

Is Base64 encryption?

No. Base64 is encoding, not encryption. It can be easily decoded by anyone. Do not use it to protect sensitive data.
