What this tool does
Base64 represents the UTF-8 bytes of text as ASCII characters, including multilingual text and emoji. It is reversible encoding, not encryption, and does not protect sensitive information.
- The encoding results can be safely copied as plain ASCII text.
- Base64 typically increases data size by about a third.
- Encoding does not provide confidentiality and sensitive content should remain protected as is.
How to use it
- Enter any UTF-8 text.
- Click "Base64 Encoding".
- Verify the resulting Base64 string.
- Click "Copy" to save the results.
Common uses
- Represents a short snippet of text in JSON or configuration.
- Test Basic data encoding and message content.
- Confirm UTF-8 byte encoding results for multilingual text.
Base64 Encode Features
Encode UTF-8 text to Base64, correctly supporting Chinese, Japanese and emoji. Review the result, then copy it for use.
FAQ
Is Base64 encryption?
No. Anyone can decode Base64, it only changes the representation and provides no cryptographic protection.
Why can Chinese be encoded normally?
The tool explicitly converts Unicode text to UTF-8 bytes first and then encodes the bytes to Base64.
Will emoji be lost?
No. Supported emoji are encoded with their complete UTF-8 content.
