Binary ↔ Text Converter
Convert text to binary and decode binary back into readable text.
Convert Between Text and Binary
Turn any text into its binary representation, where each character becomes an 8-bit sequence of zeros and ones. You can also paste space-separated binary and decode it straight back into text.
How it works
- Each character becomes 8 binary digits
- Groups are separated by a single space
- Decodes space-separated binary back to text
- Unicode characters are fully supported
To encode or decode
Type text and press "To Binary" to encode it. Paste binary digits and press "To Text" to decode them back into characters.
Why 8 bits per character
A single byte is eight bits, which is enough to represent 256 distinct values — the range of basic ASCII characters. Padding each character to 8 digits keeps the output aligned and makes it unambiguous to decode.
