Six Conversion Modes

Text to Binary converts each character to its 8-bit binary representation. Binary to Text decodes binary sequences back to readable text. Decimal to Binary converts decimal numbers to binary. Binary to Decimal converts binary numbers back to decimal. Hex to Text decodes hexadecimal values to text. Text to Hex converts text characters to hexadecimal values.

Understanding Binary and ASCII

Binary is a base-2 number system using only 0 and 1. ASCII (American Standard Code for Information Interchange) assigns a unique number (0-127) to each character. When converting text to binary, each character is first looked up in the ASCII table to get its number, which is then converted to an 8-digit binary number. For example, the letter 'A' has ASCII code 65, which is 01000001 in binary.

Frequently Asked Questions

Binary code is a system of representing text, characters, and instructions using only two digits: 0 and 1. Each letter, number, and symbol is represented by a unique sequence of 8 binary digits (called a byte). For example, the letter "A" is represented as 01000001 in binary. This is the fundamental language that computers use to process and store data.
To convert text to binary, each character is converted to its ASCII code number, which is then converted to an 8-digit binary number. For example, "H" has ASCII code 72, which is 01001000 in binary. Our converter does this automatically — just type or paste your text into the Text to Binary tab and click Convert.
ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns a unique number (0-127) to each letter, digit, punctuation mark, and control character. For example, "A" is 65, "a" is 97, "0" is 48. Extended ASCII uses numbers 0-255. This standard allows computers to consistently represent and exchange text data.
Hexadecimal (hex) is a base-16 number system using digits 0-9 and letters A-F. To convert hex to text, each pair of hex digits represents one character. For example, "48" is "H" and "65" is "e". Use the Hex to Text tab on our converter — paste hex values (with or without spaces) and click Convert to get the text.
