Convert words, symbols, and emoji into UTF-8 binary bytes.
Encode me 01000101 01101110 01100011 01101111 01100100 01100101 00100000 01101101 01100101 A text-to-binary conversion starts with an encoding, not with a mysterious alphabet. EncodeLab turns each character into UTF-8 bytes and writes every byte as eight binary digits: A becomes 01000001, while Hi becomes 01001000 01101001.
Plain English letters use the same byte values in ASCII and UTF-8. Characters outside the ASCII range, including accented letters and emoji, use two or more UTF-8 bytes, so the binary output can be longer than the visible text.
A becomes 01000001 because its ASCII value is 65. The word Hello becomes 01001000 01100101 01101100 01101100 01101111. The spaces separate bytes; they are formatting, not extra data.
Quick reference
Each word is written as UTF-8 bytes, with one space between every 8-bit group.
| Word | Binary |
|---|---|
| A | 01000001 |
| Hi | 01001000 01101001 |
| Hello | 01001000 01100101 01101100 01101100 01101111 |
| OK | 01001111 01001011 |
Text is first encoded into bytes. Each byte is then written as an eight-digit base-2 number.
No. EncodeLab performs this conversion locally in your browser. Your input is not sent to an EncodeLab server or stored by us.
Yes. Emoji are encoded as UTF-8 and usually produce multiple binary bytes.
Spaces separate individual bytes and make the binary easier to read and decode.
