Invalid binary input. Each group must be 8 bits (e.g. 01001000).
How Binary Encoding Works
Every character on a computer is stored as a number. The ASCII/Unicode standard assigns a number to each character (e.g., H = 72). Binary represents these numbers in base-2 using only 0s and 1s. This tool encodes each character as an 8-bit binary string (one byte), so the letter H becomes 01001000.
How to Use the Binary/Text Converter
- Text → Binary: Type or paste text, click “Text → Binary”. Each character becomes 8 bits, separated by spaces.
- Binary → Text: Paste binary code with 8-bit groups separated by spaces, click “Binary → Text”.
- This tool works with ASCII characters (0–127). Extended Unicode characters may produce multi-byte output.
Example
The word Hello in binary:
01001000 01100101 01101100 01101100 01101111
