Text to Binary Converter
Instantly convert any text message into binary code. Free, private, and fast — encoding runs entirely in your browser.
How to convert text to binary by hand
A text to binary converter maps each character to its numeric code (via UTF-8), then writes that number in base 2 with eight bits per byte.
- Pick a character (example: H).
- Find its ASCII code — H = 72. Use the ASCII table if needed.
- Convert 72 to binary with powers of 2: 64+8 = 72 →
01001000. - Repeat for every character and join the bytes with spaces.
H (72) → 01001000
i (105) → 01101001
Hi → 01001000 01101001

Frequently Asked Questions
How do I convert text to binary online?
Type or paste your text into the converter. Each character is encoded to UTF-8 bytes, and each byte is shown as an 8-bit binary string (for example A → 01000001).
Does text to binary support special characters?
Yes. The converter uses UTF-8, so emoji, accented letters, and symbols are supported. Multi-byte characters produce multiple 8-bit groups.
Is this text to binary tool free?
Completely free — no account, no daily limits, and conversion stays on your device.
What is the binary for “Hello”?
H=01001000, e=01100101, l=01101100, l=01101100, o=01101111 — so Hello = 01001000 01100101 01101100 01101100 01101111.
How do I convert text to binary by hand?
For ASCII, convert the character code to an 8-bit byte (A=65 → 01000001). For other text, encode it as UTF-8 first and convert each resulting byte. Join the bytes with spaces.
