How to use the Base64 Encoder / Decoder
Encode any text — including Unicode and emoji — to Base64, or decode Base64 back to readable text.
Steps
- Choose Encode or Decode mode.
- Paste your text (or Base64 string), then click Convert.
- Copy the result with the Copy button.
Unicode characters are handled correctly, so multi-byte characters like emoji survive the round trip.
