About Text to Binary
The Text to Binary Converter is a free online tool that converts any text, sentence or string into its binary (base-2) representation — a sequence of 1s and 0s. Every character in computing is stored as a binary number: this tool makes that encoding visible and easy to generate for any input text.
Binary encoding is fundamental to understanding how computers store and transmit all forms of data. This converter uses standard ASCII encoding where each character maps to an 8-bit binary number.
How to Convert Text to Binary
- Type or paste your text into the input field
- Click Convert to Binary
- The binary output appears — each character is shown as an 8-bit group separated by spaces for readability
- Copy the binary output with one click
Encoding Example
- "Hello" converts to: 01001000 01100101 01101100 01101100 01101111
- H = 01001000, e = 01100101, l = 01101100, l = 01101100, o = 01101111
Common Uses
- Learning binary encoding for computer science coursework
- Encoding messages in binary for puzzles, games or steganography
- Demonstrating how text is stored in computer memory
- Debugging character encoding issues in data systems

Frequently Asked Questions
What is binary code?
Binary code represents text using only two digits: 0 and 1. Each character is encoded as an 8-bit sequence (a byte), where each bit position represents a power of 2. For example, the letter "A" is 01000001 in binary.
What encoding does this use?
This tool uses ASCII / UTF-8 encoding, where each character maps to a standard numeric code which is then represented in 8-bit binary. Standard Latin characters all fit within a single byte.
Can I convert binary back to text?
Yes — use our Binary to Text tool to reverse the conversion. Paste your binary string (groups of 8 digits separated by spaces) and click Convert to get the original text back.
What file types can I upload?
You can upload plain text files (.txt) using the Load File button. The tool reads the file content and automatically places it in the input field, ready for conversion.
