Encode and decode UTF-8 text with Base64 in your browser. Unicode-ready and never sent to a server.

What is Base64 Encoder / Decoder?

Base64 represents binary data using ASCII characters. It is an encoding, not encryption; anyone can decode it. Use it for transport formatting, not to secure secrets.

How to use this tool

  1. Enter text or Base64 input.
  2. Choose Encode or Decode.
  3. Copy the converted output or fix the displayed validation error.

Example

Hello → SGVsbG8=
