Text to Binary Converter — ASCII, Hex, Decimal & Octal
Convert any text to binary code, hexadecimal, decimal, or octal in one click. Decode binary back to text just as easily. Supports ASCII and full Unicode/UTF-8. Perfect for students, developers, and anyone learning digital encoding.
⚡ All conversions happen in your browser. Zero data stored.
What is a Text to Binary Converter?
A Text to Binary Converter translates human-readable text into binary code — the language of computers, made up entirely of 0s and 1s. Each character in your text has a numeric code (ASCII or Unicode), and binary is simply that number expressed in base-2 (powers of 2).
For example, the letter A has ASCII value 65, which in binary is 01000001. This tool also converts to hexadecimal (base 16), decimal (base 10), and octal (base 8), making it ideal for students learning number systems, developers debugging encoding issues, and anyone curious about how computers store text.
How to Use the Text to Binary Converter
Choose a Tab — "Text to Binary" to encode, "Binary to Text" to decode, or "All Bases" for a complete number-system breakdown.
Type or Paste Your Input — The conversion updates live as you type, so you see results immediately.
Copy or Download — Use the Copy button next to any output to grab the result, or download as a .txt file.
Frequently Asked Questions
How do I convert text to binary?
Each character in your text has an ASCII code point (e.g., 'A' = 65). Converting to binary means expressing that number in base-2. 65 in binary is 01000001. This tool handles the conversion instantly for any text.
What is binary encoding?
Binary encoding represents data as sequences of 0s and 1s. Every piece of digital information is ultimately stored as binary. ASCII encodes English characters in 7-8 bits; UTF-8 extends this to support thousands of international characters.
Can I convert binary back to text?
Yes. Use the Binary to Text tab — paste space-separated 8-bit binary groups and the tool decodes them back to readable text instantly.
What is the difference between ASCII and Unicode?
ASCII uses 7-8 bits per character and covers only English + basic symbols (128-256 characters). Unicode supports over 1 million characters from all world languages. UTF-8 is the most common Unicode encoding and is backward-compatible with ASCII.
What is hexadecimal (hex)?
Hexadecimal is base-16, using digits 0-9 and letters A-F. It's widely used in programming to represent binary more compactly — each hex digit represents exactly 4 bits (one nibble). For example, 'A' (65) in hex is 41.
