Frequently asked questions
Does it handle emoji and non-English text?+
Yes. Encoding and decoding are fully Unicode-safe using UTF-8, so emoji and accented characters round-trip correctly.
Is my data sent to a server?+
No. Encoding and decoding happens entirely in your browser using built-in web APIs — nothing is uploaded, stored, or logged.
