About Base64 Encoder & Decoder

Convert UTF-8 text to Base64 and decode Base64 back to text. Base64 is an encoding, not encryption, so anyone can reverse it.

How to use it

  1. Paste text or Base64.
  2. Choose encode or decode.
  3. Run the conversion and copy the result.

Frequently asked questions

Is Base64 secure encryption?

No. Base64 is easily reversible and should not be used to protect secrets.

Does it support Unicode text?

Yes. The encoder uses UTF-8, and the decoder expects valid UTF-8.
