How this works
Base64 Encoder / Decoder runs as plain JavaScript inside this page using the browser's own Web Crypto and text APIs. There is no request to our server when you press the button, so nothing you enter leaves your device.
Base64 Encoder / Decoder
Encode text to Base64 or decode Base64 back to UTF-8 text.
