What is Binary and Hexadecimal?
Binary (base-2) and hexadecimal (base-16) are numeral systems used extensively in computing. While humans use decimal (base-10), computers store all data as binary—ones and zeros. Hexadecimal provides a more compact, human-readable way to represent binary data.
This free converter transforms text to binary, hexadecimal, octal, or decimal representations and back. It's essential for programmers, security researchers, and anyone working with low-level data representation.
Understanding Number Systems
| System | Base | Characters | "A" Example |
|---|---|---|---|
| Binary | 2 | 0, 1 | 01000001 |
| Octal | 8 | 0-7 | 101 |
| Decimal | 10 | 0-9 | 65 |
| Hexadecimal | 16 | 0-9, A-F | 41 |

Common ASCII Values
Frequently Asked Questions
Why 8 bits per character?
ASCII uses 7 bits (128 characters), but computers work in bytes (8 bits). Extended ASCII and UTF-8 use the extra bit, and padding to 8 bits simplifies storage and processing.
Does this work with Unicode/emojis?
Yes! Each Unicode character is converted to its code point. Note that emojis and special characters may produce multiple bytes in UTF-8 encoding.
Is binary the same as encryption?
No. Binary is just a different representation of the same data—it's easily reversible. Encryption uses complex algorithms to make data unreadable without a key.
