  2. Choose encode or decode.
  3. Copy the result.

Frequently asked questions

Is encoding the same as encryption?
No. Encoding is a reversible format change with no secret key involved, so it provides no security at all. Use real encryption for sensitive data.
Is my data uploaded?
No. Encoding and decoding both run entirely in your browser.
Does it handle Unicode and emoji?
Yes. Non-ASCII characters and emoji are handled correctly in both directions.
