Hex to Binary Converter Online
Hexadecimal (hex) and binary are both number systems used in computing. The binary is a base2 number system, meaning it uses only two digits, 0 and 1, to represent any number. Hexadecimal is a base16 number system, which uses 16 digits, 09 and AF, to represent numbers.
How to convert hex into binary?
To convert a hexadecimal number to binary, you can follow these steps:
 Write down the hex number you want to convert.
 Write down the binary value of each hex digit, according to the following table:
Hex Digit  Binary Value 

0  0000 
1  0001 
2  0010 
3  0011 
4  0100 
5  0101 
6  0110 
7  0111 
8  1000 
9  1001 
A  1010 
B  1011 
C  1100 
D  1101 
E  1110 
F  1111 
 Combine the binary values of each hex digit to get the binary representation of the whole hex number.
For example, let's convert the hex number "3F" to binary:
 The hex number is "3F".
 The binary value of "3" is "0011", and the binary value of "F" is "1111".
 Combining the binary values gives us "00111111", which is the binary representation of the hex number "3F".
We hope this helps!
What is 255 hex in binary?
To convert the hex number 255 to binary, we can follow the steps I outlined earlier:
 Write down the hex number 255.
 Write down the binary value of each hex digit using the table in my previous response. The hex digit "2" has a binary value of "0010", and the hex digit "5" has a binary value of "0101".
 Combine the binary values of each hex digit to get the binary representation of the whole hex number. In this case, we get "0010 0101" (note that the space between the two nibbles is optional).
Therefore, the binary representation of the hex number 255 is "00100101".
What is RGB 255,255,255 in hex?
To convert an RGB color value to hex, we can convert the decimal values of each color channel (red, green, and blue) to their hex equivalent and concatenate them.
In this case, we have an RGB value of 255, 255, 255. To convert each decimal value to hex, we can use the following table:
Decimal  Hex 

0  00 
1  01 
2  02 
...  ... 
253  FD 
254  FE 
255  FF 
Using this table, we can convert each decimal value to hex:
 255 decimal = FF hex
 255 decimal = FF hex
 255 decimal = FF hex
So the RGB value 255,255,255 in hex is #FFFFFF.
How to convert hex to binary in js?
In JavaScript, you can use the parseInt()
function with a radix of 16 to convert a hexadecimal string to an integer, and then use the toString()
method with a radix of 2 to convert the integer to binary.
Here's an example function that converts a hexadecimal string to binary in JavaScript:
function hexToBinary(hexString) {
In this function, we first use
const decimalNumber = parseInt(hexString, 16);
const binaryString = decimalNumber.toString(2);
return binaryString.padStart(hexString.length * 4, '0');
}parseInt()
to convert the input hexString
to a decimal number using a radix of 16. We then use the toString()
method with a radix of 2 to convert the decimal number to a binary string. Finally, we use the padStart()
method to add leading zeros to the binary string so that it has the same number of bits as the original hexadecimal string.
When converting hex to binary What should you do first?
When converting a hexadecimal number to binary, the first thing you should do is write down the binary equivalent of each hexadecimal digit. You can use the following table to find the binary equivalent of each hex digit:
Hex Digit  Binary Value 

0  0000 
1  0001 
2  0010 
3  0011 
4  0100 
5  0101 
6  0110 
7  0111 
8  1000 
9  1001 
A  1010 
B  1011 
C  1100 
D  1101 
E  1110 
F  1111 
After you have written down the binary value of each hexadecimal digit, you can combine the binary values to get the binary representation of the entire hexadecimal number.
For example, if you want to convert the hexadecimal number "3F" to binary, you would first write down the binary value of each hexadecimal digit: "0011" for 3 and "1111" for F. You would then combine these two values to get "00111111", which is the binary representation of the hexadecimal number "3F".
What are the benefits of converting hex to binary?
Converting hexadecimal numbers to binary has several benefits:

Compactness: Binary numbers are more compact than hexadecimal numbers. For example, a byte can be represented using 8 binary digits (bits) or 2 hexadecimal digits. This means that binary numbers take up less storage space than their equivalent hexadecimal numbers.

Ease of conversion: Converting hexadecimal to binary is easier than converting to decimal, especially for people who are used to working with computers. Hexadecimal numbers can be easily converted to binary by replacing each hexadecimal digit with its 4bit binary equivalent.

Representation of memory addresses: Memory addresses in computers are typically represented in hexadecimal or binary format. Converting hexadecimal addresses to binary can make it easier to visualize how data is stored in memory and how it can be accessed.

Networking: In networking, hexadecimal numbers are often used to represent MAC addresses, which identify network devices. Converting these addresses to binary can make it easier to manipulate and compare them.
Overall, converting hexadecimal numbers to binary can make it easier to work with and understand computer systems and data.
Why do computer scientists prefer hex to binary?
Computer scientists often prefer hexadecimal to binary for several reasons:

Compactness: Hexadecimal numbers are more compact than binary numbers. A byte, for example, can be represented by two hexadecimal digits or eight binary digits (bits). This means that hexadecimal numbers take up less space when stored or transmitted.

Ease of conversion: Converting binary to hexadecimal is easier than converting to decimal because each hexadecimal digit corresponds to a group of four binary digits. This makes it easier for computer scientists to work with and manipulate data represented in hexadecimal format.

Readability: Hexadecimal numbers are more humanreadable than binary numbers. Hexadecimal digits are represented using the numbers 09 and the letters AF, which are easier to distinguish and remember than long strings of 1s and 0s.

Memory representation: Memory addresses and other data in computer systems are often represented in hexadecimal format. Converting these values to binary can make it easier to understand how data is stored and accessed in memory.

Debugging: In some cases, hexadecimal numbers can make it easier to debug programs. For example, memory dumps and other lowlevel system data are often represented in hexadecimal format. Being able to read and understand this data can help computer scientists diagnose and fix problems in their code.
Overall, hexadecimal is a convenient and widely used format for representing data in computer systems, and it offers several advantages over binary for many applications.

What is the range of hexadecimal?
In hexadecimal (base 16), the digits range from 0 to 9, and then from A to F. The range of values that can be represented by a single hexadecimal digit is 0 to 15 (decimal), which can be represented by the binary numbers 0000 to 1111.
In terms of the total range of values that can be represented in hexadecimal, it depends on the number of hexadecimal digits being used. For example:
 One hexadecimal digit can represent 16 values (0 to 15).
 Two hexadecimal digits can represent 256 values (0 to 255).
 Three hexadecimal digits can represent 4,096 values (0 to 4,095).
 Four hexadecimal digits can represent 65,536 values (0 to 65,535).
 And so on...
In general, the range of values that can be represented in hexadecimal grows exponentially with the number of digits used.
Does hexadecimal take less space?
Yes, hexadecimal takes up less space than binary when representing large numbers. For example, a 32bit number (which can represent values from 0 to 4,294,967,295) can be represented using either 32 binary digits (bits) or 8 hexadecimal digits.
In binary, the number 4,294,967,295 would be represented as:
11111111111111111111111111111111
In hexadecimal, the same number would be represented as:
FFFFFFFF
As you can see, the hexadecimal representation is shorter and more compact than the binary representation. This means that hexadecimal is often used in computer systems to represent large numbers or blocks of data, as it takes up less storage space than its binary equivalent.
Is hexadecimal better?
"Better" is subjective and depends on the context in which hexadecimal is being used. However, there are several advantages to using hexadecimal in certain situations:
