Base64 Encoder & Decoder

Encode text to Base64 or decode Base64 back to UTF-8 text.

How it works

Text is encoded as UTF-8 before Base64 conversion. Base64 is an encoding, not encryption.

UTF-8 text ↔ binary bytes ↔ Base64.

Common questions

Is Base64 secure?

No. Anyone can decode it. Do not use it to protect secrets.

Are Unicode characters supported?

Yes, the tool converts UTF-8 text before encoding.
