Free online text to binary converter
This text to binary converter turns any message into binary code and decodes it back again. It is great for learning how computers store text, for puzzles and geeky gifts, or for understanding character encoding.
How text becomes binary
Computers store every character as a number. The letter “H” is 72, which in binary is 01001000. Each character maps to one byte — eight bits — following the ASCII and UTF-8 standards. Put the bytes side by side and you have the binary for a whole message.
UTF-8 for every language
This tool uses UTF-8, the encoding of the modern web. Plain English letters stay at one byte each, while emoji, accented letters and other scripts use several bytes — all handled automatically. Because it runs in your browser, conversion is instant, private and works offline.
Frequently Asked Questions
How do I convert text to binary?
Type your text and each character is converted to its 8-bit binary code. For example, 'Hi' becomes 01001000 01101001. Each group of eight bits is one byte (one character).
How do I convert binary back to text?
Switch to Binary → Text mode and paste your binary in 8-bit groups separated by spaces. The tool decodes each byte back into the original characters.
Why is each character eight bits?
Basic characters use one byte, which is eight bits, following ASCII. This tool uses UTF-8, so standard English letters are eight bits while emoji and accented characters may use several bytes.
Does it support emoji and other languages?
Yes. Text is encoded as UTF-8, so emoji, accented letters and non-Latin scripts convert correctly — they simply use more than one byte each.
What is the binary for a space?
A space is character 32, which is 00100000 in binary. Punctuation and digits each have their own byte value too.
Is my text private?
Yes. Conversion happens entirely in your browser. Nothing is uploaded, and the tool works offline.
