Question 1

Does Base64 work with emoji and accents?

Accepted Answer

Yes. Text is encoded as UTF-8 first, so any Unicode character survives the round trip.

Question 2

Is Base64 encryption?

Accepted Answer

No. It is only a way of writing data in plain ASCII — anyone can decode it, so never use it to protect secrets.

Question 3

Is it really free, and do I need an account?

Accepted Answer

Yes, it is completely free and there is no sign-up, watermark, email wall or daily limit.
