How to use it
A clear, quick workflow
- Choose Encode or Decode.
- Paste or type the input.
- Copy the converted output or swap it back into the input.
Base64 Text Encoder & Decoder
Encode or decode Unicode text with strict Base64 handling.
Start typing to convert.
Example
“Merhaba 👋” encodes to TWVyaGFiYSDwn5GL.
Limits and behavior
Input is limited to 1,000,000 JavaScript characters. Decode accepts ASCII spaces, tabs, and line breaks, but rejects malformed padding, non-Base64 symbols, and invalid UTF-8.
FAQ
Is Base64 encryption?
