How do I convert text to binary?

Type or paste your text into the input box. The tool encodes each character as UTF-8 bytes and shows each byte as an 8-bit binary number, separated by spaces.

How is each character represented?

Standard ASCII characters become a single 8-bit byte. Characters outside ASCII (accents, emoji) are encoded as their multi-byte UTF-8 sequence, so each becomes two to four 8-bit bytes.

Can I convert the binary back to text?

Yes. Use the Binary to Text converter, which reads 8-bit binary groups (space-separated or continuous) and decodes them back to readable text.

Is my text sent to a server?

No. All encoding happens locally in your browser; nothing is uploaded or stored.
