Binary Translator — Text to Binary & Binary to Text

What the Binary Translator does

This tool turns text into binary (the 0s and 1s computers store) and turns binary back into readable text. Each character is first encoded as UTF-8 bytes, and each byte is shown as a group of 8 bits, so the letter A becomes 01000001. Because it uses UTF-8, accented letters, symbols and emoji work too.

How to use it

1. Type or paste your text into the left-hand box.
2. Click Convert. The binary appears on the right as space-separated 8-bit groups.
3. To go the other way, click Swap, paste your binary (only 0, 1, spaces and new lines) and click Convert.
4. Click Copy to copy the result, or Clear to start again.

Worked examples

Text to binary: Hi → 01001000 01101001 (H is byte 72, i is byte 105).

Binary to text: 01001111 01001011 → OK (bytes 79 and 75).

FAQ

Why is every group 8 digits long?

One byte is 8 bits. Leading zeros are kept so every byte has the same width, which makes the output easy to read and to convert back.

Why does one character sometimes become two or more groups?

In UTF-8, plain English letters, digits and common punctuation take one byte. Other characters take more: é is two bytes, and many emoji are four.

What happens if my binary contains other characters?

The converter shows an error instead of guessing. Binary input may only contain 0, 1, spaces and new lines.

Is my text sent anywhere?

No. The conversion runs entirely in your browser; nothing you type is sent to TechyHunt or anyone else.
