Base64 encoder
Encode Unicode text as Base64 safely.
Encode text as standard Base64 using its UTF-8 bytes. This supports non-English text as well as ASCII. Base64 is a reversible representation for moving data between systems; it does not encrypt or protect the text.
How to use
- Type or paste the text you want to encode.
- Run the tool to encode the text as UTF-8 Base64.
- Copy or download the encoded string.
Worked example
Example input
Hello 世界
Example result
SGVsbG8g5LiW55WM
Limitations and details
This is a text encoder, not a binary-file encoder. It produces standard Base64, not the URL-safe variant. Anyone can decode the result, so encoding a password or token does not make it safe to share.
