Frequently asked questions
Is my text sent anywhere?
No. The transformation happens in your browser with plain JavaScript — nothing you type or paste leaves your device.
Why does one emoji become several bytes?
Characters outside ASCII are encoded as multiple UTF-8 bytes — an emoji is typically 4 bytes, so you'll see four 8-bit groups.
