Frequently Asked Questions

Is Base64 encryption?

No, it is an encoding, not encryption. Anyone can decode it; it just makes binary data text-safe.

Why do results end with =?

= is padding to make the output length a multiple of 4.

Does it support Chinese/emoji?

Yes, input is UTF-8 encoded before conversion.
