What is Binary?
Binary is the most fundamental numbering system used by computers. It uses only two digits: 0 and 1. These digits, called bits, are combined to represent all types of data in digital systems, including text, images, and programs.
This free online tool converts text to its binary representation (encoding) or converts binary back to readable text (decoding). It supports various formats including space-separated bytes, continuous binary strings, and more.

How Binary Encoding Works
Character Codes
Each character has a numeric code (like ASCII or Unicode). For example, 'A' is 65, 'B' is 66, and so on. These numbers are then converted to binary.
8-Bit Bytes
Standard encoding uses 8 bits per character (a byte). Each byte can represent values from 0 to 255, which covers all ASCII characters and more.
Reading Binary
Binary is read from right to left, where each position represents a power of 2. For example, 01000001 = 64+1 = 65 = 'A'.
UTF-8 Support
This tool supports UTF-8 encoding, which means it can handle characters from any language, including emojis and special symbols.
Frequently Asked Questions
What's the difference between 8-bit and 7-bit?
8-bit (standard) uses 8 binary digits per character, supporting values 0-255. 7-bit is for original ASCII which only uses values 0-127. Most modern applications use 8-bit encoding.
Why do some characters produce multiple bytes?
UTF-8 is a variable-length encoding. Basic ASCII characters use 1 byte, but characters from other languages or emojis may use 2, 3, or even 4 bytes to represent their full Unicode values.
Can I use different separators?
Yes! When encoding, you can choose between spaces, commas, newlines, or no separator. When decoding, the tool automatically detects common separators including spaces, commas, and dashes.
Is my data sent to a server?
No. All conversion happens entirely in your browser using JavaScript. Your data never leaves your device, making this tool completely private and secure.
