Use the text tab to encode and decode plain text, or the file tab to convert files to Base64 and vice-versa.

Very large files may cause the browser to freeze since processing is done in memory.

This tool processes everything locally in your browser. No data is sent to the server.

Ensure text is valid Base64 when decoding, otherwise an error will be thrown.

Base64 is an encoding scheme that represents binary data in an ASCII string format.
