Privacy-first Base64 tools
Base64 Encoder Pro is designed so encoding and decoding happens client-side in your browser. Text, files, JWTs, and image data you process with the tool are not sent to a Base64 Encoder Pro server for conversion.

What this site stores and processes
Browser-only conversion
Encoding and decoding operations run locally with JavaScript in your web browser. The content you enter into the encoder, decoder, JWT decoder, bulk processor, or image data-URI tool is processed on your device.
No server upload for tool input
Base64 Encoder Pro does not require an account and does not upload your input or output to our server for storage, logging, encoding, or decoding.
localStorage
The tool uses your browser's localStorage to save recent conversion history under base64-history, your theme preference under base64-theme, and your cookie notice choice under base64-cookie-consent. This data stays in your browser unless you clear it or your browser removes it.
