faq ▸ before you buy

Is Base64 encryption?+

No. Base64 is an encoding — anyone can reverse it instantly. Use real encryption for secrets.

Why is Base64 output bigger than the input?+

Every 3 bytes become 4 characters, so encoded data is about 33% larger.

Does it support Hindi and other Unicode text?+

Yes. Text is converted to UTF-8 bytes before encoding, so any language and emoji round-trips correctly.
