Base64 Encode
Type or paste text and get its Base64 encoding live as you type. Encoding is UTF-8-aware, so emoji and non-Latin scripts round-trip correctly — unlike naive btoa() usage.

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.
Does this handle Unicode and emoji?
Yes — text is UTF-8 encoded before Base64, so any character round-trips correctly. Plain btoa() in JavaScript breaks on non-Latin text; this tool doesn't.
