Browser-only converter
Encode and decode Base64 text or files
Convert plain text to Base64, decode Base64 back to readable text, load a small local text file, and download the result without sending anything to a server.
Plain text or Base64
Files are read locally in your browser. Best for small text files up to about 1 MB.
Output
Choose Encode or Decode.
Private: pasted text and opened files are processed locally in your browser; nothing is uploaded.
Unicode-safe: emojis and accented characters are encoded with UTF-8 instead of old ASCII-only shortcuts.
Exportable: copy the result or download it as a simple `.txt` file for notes, fixtures, or config snippets.
Encode text or files
Turn pasted text, config snippets, JSON fixtures, Markdown notes, or small local text files into Base64 for quick sharing or debugging.
Decode safely
Paste Base64 and get a clear UTF-8 text result or a useful error if the input is malformed or binary-only.
Copy or download
Bizzon does not upload or store the text you paste or open. Copy the result or download it as a simple text file.
