Frequently asked questions

Is Base64 encryption?

No. Base64 is encoding, not encryption — it only changes the representation, not the security. Anyone can decode it, so never use it to protect passwords or secrets.

Does it support special characters and emoji?

Yes. Text is treated as UTF-8, so accents, Cyrillic, emoji and any Unicode round-trip correctly.

Is my text sent anywhere?

No. Encoding and decoding happen entirely in your browser; nothing is uploaded.
