Binary to ASCII Converter

Convert binary numbers to ASCII character codes instantly.

About Binary to ASCII Converter

The Binary to ASCII Converter transforms binary (base-2) numbers back into ASCII character codes. This is useful when working with raw binary data, decoding messages, or understanding how computers process text at the lowest level.

Enter binary numbers separated by spaces and the tool will decode them into their corresponding ASCII decimal codes. You can also optionally view the text characters these codes represent.

How to Use

1

Enter Binary

Type binary numbers (sequences of 0s and 1s) separated by spaces. Each group represents one ASCII character.

2

Select Bit Length

Choose 8-bit for standard binary or 7-bit for original ASCII format.

3

Convert

Click "Convert to ASCII" to see the decoded ASCII codes and optionally the text representation.

Frequently Asked Questions

What is the binary for 'A'?

The uppercase letter 'A' is represented as 01000001 in 8-bit binary (65 in decimal). Each character in ASCII has a unique binary code.

How do I read binary numbers?

Each position in a binary number represents a power of 2, starting from the right (1, 2, 4, 8, 16, 32, 64, 128). Add the values where there is a 1. For example, 01000001 = 64 + 1 = 65.

What if my binary has no spaces?

If the binary input has no spaces, the tool will split it into groups of the selected bit length (8 or 7 bits each). Make sure the total length is a multiple of the bit length.

Is this tool secure?

Yes, all conversions happen locally in your browser. No data is sent to any server.
