Convert text to binary code and binary back to text, or show the bytes in hexadecimal, decimal and octal.
Type in the top box to see your text as binary code, or paste binary into the bottom box to decode it. You can also show the same bytes in hexadecimal, decimal or octal, which is useful for programming and computer science homework.
| Character | Decimal | Binary | Hex |
|---|---|---|---|
| A | 65 | 01000001 | 41 |
| a | 97 | 01100001 | 61 |
| 0 | 48 | 00110000 | 30 |
| space | 32 | 00100000 | 20 |
Prefer dots and dashes? Try the Morse code translator. Developers can also encode text with Base64.
Each character is stored as one or more bytes using UTF-8, the encoding used by almost every website. Each byte is 8 bits, written as eight 0s and 1s. For example, “A” is 65, which is 01000001 in binary.
UTF-8 uses one byte for basic English letters and numbers, but two to four bytes for accented letters, other alphabets and emoji. So “é” is 2 bytes and 😀 is 4.
Yes. Paste binary into the bottom box. Spaces between bytes are optional: a continuous string of 0s and 1s is split into groups of eight.
