Convert text to binary and back — instant, client-side conversion
Binary is a base-2 number system using only digits 0 and 1. Every piece of data stored on computers—from text to images—is ultimately represented in binary. When you convert text to binary, each character is first converted to its ASCII value, then that value is converted to an 8-bit binary number. For example, the letter "A" has ASCII value 65, which is 01000001 in binary.
Binary conversion is useful in computer science education, debugging, understanding how computers store data, and in some programming tasks. Developers often need to work with binary representations when dealing with bit flags, binary protocols, or embedded systems. Understanding binary helps you grasp fundamental computer concepts and appreciate how digital systems work at the lowest level.
This converter handles two-way conversion seamlessly. For text-to-binary, each character is converted to its ASCII code and then to its 8-bit binary representation. For binary-to-text, the reverse process occurs—binary strings are grouped into 8-bit bytes, converted to ASCII values, and then to their text equivalents. All processing happens locally in your browser. For related conversions, try our Text Hexadecimal Converter or Text Decimal Converter tools.
Explore other encoding formats with our Text Hexadecimal Converter, Text Decimal Converter, Text Octal Converter, Base64 Encoder/Decoder, or URL Encoder/Decoder. For cryptographic hashing, check out our MD5 Hash Generator or SHA256 Hash Generator.
This tool primarily handles ASCII (0-127). For Unicode and extended characters, results may vary. Standard ASCII text works perfectly.
Enter binary as 8-bit groups (bytes) separated by spaces, like "01000001 01000010 01000011". Spaces between bytes are recommended but not required for some formats.
No practical limit—convert as much text as you need. All processing is instant and client-side.
