Binary to ASCII

ASCII (American Standard Code for Information Interchange) is a character encoding standard found in many computers and digital systems. ASCII maps human characters (such as Aa, Bb, Cc) to 7-bit binary numbers that can be processed by computers. In the standard ASCII set, there are 128 characters, including all lowercase and uppercase letters, the digits 0-9, common symbols such as (+-./-<>) and some control characters.

If working at a binary level within a system then it may be useful to map these binary to ASCII characters. You can check you have done this correctly with our free binary to ASCII converter above or in our handy conversion table below.

How to convert binary to ASCII code?

To convert binary to ASCII code manually you should follow our step-by-step procedure below:

1. First we need to group the binary digits in bytes (8-bits).
2. This means that each group now corresponds to 1 ASCII character.
3. For each 8 group bit convert the binary number to decimal. If you don’t know how to do this take a look at our free binary-to-decimal converter or print out a copy of the binary-to-decimal conversion table.
4. Look up the decimal number in an ASCII table below to find the corresponding character.
5. Combine all characters to complete your result.

How to use the binary to ASCII converter

1. Enter you number in binary (1s and 0s) in the top input box.
2. You can seperate text characters by spaces.
3. Click convert to convert the binary input to ASCII. The result will be found below.
4. You can copy the input using the copy button above the calculator.
5. You can reset the input with the reset button also above the calcualtor.
