Binary to ASCII Conversion


This binary to ASCII converter helps you decode binary-encoded text and convert ASCII characters to their binary representation.

How to Use This Converter

  • Enter binary values (in 8-bit groups) to see their ASCII equivalent
  • Or type ASCII characters to view their binary representation

Supports both binary to ASCII and ASCII to binary conversion.

Understanding the Conversion

Each ASCII character is represented by an 8-bit binary number. For example, the letter "A" is 01000001 in binary.

To decode binary, split the binary input into 8-bit segments and match them with their decimal/ASCII equivalents using an ASCII table.

Example

Convert binary 01001000 01100101 01101100 01101100 01101111 to ASCII:

BinaryDecimalASCII
0100100072H
01100101101e
01101100108l
01101100108l

More About Binary

Binary (base-2) uses only 0s and 1s. Computers use binary internally to represent all data, including ASCII characters.

ASCII assigns each character a unique number between 0 and 127, which can be represented as a binary number using 7 or 8 bits.

More About ASCII

ASCII stands for American Standard Code for Information Interchange. Developed in the 1960s, ASCII became a widely adopted standard for representing letters, digits, punctuation, and control characters in computers and communication equipment.

ASCII uses 7 bits to represent each character, allowing for a total of 128 unique symbols. These include standard English letters (A-Z, a-z), digits (0-9), punctuation marks, and control codes like newline and carriage return.

Although ASCII only requires 7 bits, characters are typically stored in 8-bit bytes in modern systems. The extra bit (the most significant bit) was sometimes used for error detection or extended character sets, such as ISO 8859-1 or other encodings that support additional symbols.
