Base64 Encode / Decode
Convert between text and Base64. UTF-8 safe.
How to use
- Enter text and press "Encode", or paste Base64 and press "Decode".
- "Swap" exchanges input and result — handy for a quick round trip.
- Encoding is UTF-8, so non-ASCII text and emoji round-trip correctly.
Everything runs in your browser and is not sent anywhere.
