Frequently Asked Questions

How do I convert hex to binary?
Each hexadecimal digit maps directly to a 4-bit binary nibble. For example, hex A = 1010, hex F = 1111. To convert a hex number like 2F, convert each digit separately: 2 = 0010, F = 1111, so 2F = 00101111.
What is hexadecimal?
Hexadecimal (hex) is a base-16 number system that uses digits 0-9 and letters A-F. It's widely used in computing because each hex digit represents exactly 4 binary bits, making it a compact way to represent binary data. For example, the binary number 11111111 is just FF in hex, and the color white in CSS is #FFFFFF.
What is the binary equivalent of hex FF?
Hex FF in binary is 11111111. Each F = 1111 in binary, so FF = 1111 1111. This equals 255 in decimal and represents the maximum value of a single byte (8 bits).
What is the difference between hex and binary?
Binary is base-2 (uses only 0 and 1) while hexadecimal is base-16 (uses 0-9 and A-F). Hex is a more compact representation — one hex digit equals exactly 4 binary digits. For example, the 8-bit binary 10110110 is just B6 in hex. Hex is preferred for readability in memory addresses, color codes, and MAC addresses.
Can I convert binary back to hex?
Yes! Group the binary digits into sets of 4 from right to left, then convert each group to its hex equivalent. For example, 101101101011 0110B6. This tool supports both directions — click the "Swap Direction" button to switch from binary to hex mode.
