Binary code is a number system that uses only two digits: 0 and 1. Computers use binary to store and process all data, including text, images, and programs. Each binary digit is called a 'bit', and 8 bits make a 'byte' which can represent one ASCII character.

Bidirectional

Convert text to binary and binary back to text. Click the Swap button to switch direction instantly. Supports decimal, hex, and octal input too.

UTF-8 Support

Handle any character including emoji, accented letters, and international scripts. UTF-8 encoding preserves multi-byte characters correctly.

Frequently Asked Questions

How do I convert text to binary?

Type or paste your text into the input field and the tool instantly converts each character to its binary representation. Each ASCII character becomes an 8-bit binary number. For example, A becomes 01000001 and Hello becomes 01001000 01100101 01101100 01101100 01101111.

What is binary code?

Binary code is a number system that uses only two digits: 0 and 1. Computers use binary to store and process all data. Each binary digit is called a "bit", and 8 bits make a "byte" which can represent one ASCII character (values 0–255). Binary is the fundamental language of all digital electronics.

Can I convert binary back to text?

Yes! Click the "Swap Direction" button to switch to Binary → Text mode. Paste your binary code (space-separated 8-bit groups like 01001000 01101001) into the input field and it will be converted back to readable text.

What is the binary code for the letter A?

Uppercase A is 01000001 in binary (decimal 65). Lowercase a is 01100001 (decimal 97). The difference between uppercase and lowercase in binary is always the 6th bit (bit 5).

Does this tool support emoji and special characters?

Yes! Select "UTF-8" encoding to handle all Unicode characters including emoji, accented letters (é, ü, ñ), and characters from other scripts (Chinese, Arabic, Cyrillic). In UTF-8, each character may use 1 to 4 bytes depending on the code point.
