Text to Base64 Encoder

Text to Base64 encodes any text to Base64 in real time, handling full Unicode and emoji correctly through UTF-8. It is for developers embedding text in data URIs, tokens, or config that expects Base64.

Base64 lets text travel safely through systems that expect ASCII. Encoding locally handles Unicode correctly and keeps the text off any server.

1. Type or paste the text you want to encode.
2. It is encoded to Base64 live as you type.
3. Full Unicode and emoji are handled via UTF-8.
4. Copy the Base64 output.

• Real-time text-to-Base64 encoding
• Correct UTF-8 handling for Unicode and emoji
• Live encoded output
• Encoded in the browser

• Embedding text in a data URI
• Encoding a value for a system that expects Base64
• Preparing text for a token or header
• Teaching how Base64 encoding works

• Remember Base64 is encoding, not encryption; do not use it to protect secrets.
• Base64 grows text by roughly a third, so it suits small values rather than large blobs.
• Pair with the decoder to confirm a value round-trips back to the original.

• Assuming Base64 is encryption; it is reversible encoding, not security.
• Mishandling Unicode with a naive encoder — this one uses UTF-8 so emoji survive.
• Adding stray line breaks that some decoders reject.
