Binary / Text Converter

Free Binary to Text Converter — Convert Binary Code & Back

Binary code is the fundamental language of computers — all data is ultimately stored as sequences of 0s and 1s. Converting between binary code and readable text is a common task in programming education, cybersecurity, data encoding, and computer science study. This free Binary to Text Converter translates binary code to readable text and text back to binary instantly, with support for ASCII and extended character sets.

Paste binary code (space-separated 8-bit groups like 01001000 01100101 01101100 01101100 01101111) to decode it to text. Or type any text to encode it as binary. The tool handles the ASCII lookup table automatically for any standard or extended ASCII character.

Binary-to-text conversion is frequently needed in CTF (Capture the Flag) security challenges, programming coursework, and when debugging binary data formats, network packets, or file headers.

How Binary Text Encoding Works

ASCII encoding. The letter "A" has ASCII code 65. In 8-bit binary, 65 = 01000001. Every printable character (letters, digits, punctuation) has a corresponding binary value from 00100000 (space) to 01111110 (tilde).

Converting binary to decimal. 01001000 = 0+64+0+8+0+0+0+0 = 72 = "H". Each 8-bit group maps to one ASCII character.

Extended characters. Characters outside basic ASCII (accented letters, symbols, emoji) use UTF-8 multi-byte sequences of 16, 24, or 32 bits.
