How it works

The tool provides bidirectional conversion (You can edit either field):

  • Text to Base64: Encodes input to Base64
  • Binary to Text: Decodes Base64 data to plain text

Both fields update in real-time as you type, allowing you to see the conversion instantly.

What is Base64?

Base64 is a way to represent binary data using only readable text characters. It converts bytes (raw data) into a limited set of 64 symbols: letters, numbers, and a few symbols like + and /. This makes it safe to include binary data, such as images or files, inside text-based formats like JSON, email, or HTML without breaking them. When decoded, the original binary data is perfectly restored.

FAQ

Is my text stored or saved?
No, all analysis is done locally in your browser. Your text is not sent or stored anywhere.

Can Base64 be used as encryption? No. While Base64 makes data appear unreadable to the naked eye, it is easily reversible, so it does not provide security.
