常见问题

Does it handle special characters and emoji?

Yes, the text is encoded as UTF-8 before converting to Base64, so accented letters, symbols and emoji all round-trip correctly.

Can I encode a file, not just text?

This tool only encodes text you type or paste. It doesn't accept file uploads, so for encoding a file you'd need a dedicated file-to-Base64 tool.

Is my text sent anywhere?

No, this runs entirely in your browser using the browser's built-in Base64 encoding APIs. Nothing is sent to a server.
