How It Works
Choose Encode or Decode mode, enter your text or Base64 string, then click the button. Encoding converts text to Base64; decoding reverses it.
Base64 encoding represents binary data as printable ASCII characters. The tool handles the UTF-8 encoding step internally, so Unicode text (including accented characters and emojis) is correctly preserved in both directions.
