Free Text to Binary Converter Online
Convert text to binary and binary back to text instantly. Bidirectional ASCII to binary conversion for learning, encoding, and data processing.
What is Binary?
Binary is the base-2 number system using only 0s and 1s. Computers store all data as binary because digital circuits have two states: on (1) and off (0). Each character in text is represented by an 8-bit binary number.

How Text to Binary Works
Each text character has an ASCII code (0-255). This code is then converted to 8-bit binary:
| Character | ASCII Code | Binary |
|---|---|---|
| A | 65 | 01000001 |
| B | 66 | 01000010 |
| Z | 90 | 01011010 |
| a | 97 | 01100001 |
| 0 | 48 | 00110000 |
| Space | 32 | 00100000 |
Common Conversions
| Text | Binary |
|---|---|
| Hello | 01001000 01100101 01101100 01101100 01101111 |
| Hi | 01001000 01101001 |

FAQs About Binary Conversion
Why is each character 8 bits?
8 bits (1 byte) can represent 256 values (0-255), enough for all standard ASCII characters.
What about Unicode and emojis?
Unicode characters beyond ASCII require more than 8 bits. Our tool focuses on ASCII-compatible text.
Is binary case-sensitive?
Yes, uppercase and lowercase letters have different ASCII codes and thus different binary representations.
What if I enter invalid binary?
The tool will show an error or display an incorrect character if the binary isn't valid 8-bit patterns.
