Binary Translator — TechWhack Score

9.5/10

Privacy 10/10

The conversion runs in your browser — your text is never sent anywhere.
Speed 10/10

Text and binary convert the instant you type.
Features 8/10

Both directions, 8-bit bytes, and UTF-8 so accents and emoji round-trip; binary input can be spaced or unspaced.
Free 10/10

No sign-up, no limit.

Verdict: UTF-8 support is the bit most binary tools skip — here “é” and emoji survive the round trip instead of turning to mush.

A binary translator converts text into binary — the 0s and 1s computers use — and converts binary back into readable text. Each character becomes one 8-bit byte (the letter A is 01000001), separated by spaces, using UTF-8 so accented characters and emoji work too. Paste either way and the result appears instantly.

How text becomes binary

Every character has a number (the letter A is 65), and that number is written in base 2 as an 8-bit byte — 01000001. A space is 00100000. UTF-8 handles characters beyond basic ASCII by using more than one byte, so “é” or an emoji still round-trips correctly.

When you need it

Learning how computers store text, checking an ASCII value, a puzzle or CTF challenge, or encoding a short message in 0s and 1s for fun.

FAQ

How do I convert text to binary?Type your text and the tool writes each character as an 8-bit byte. “Hi” becomes 01001000 01101001.

How do I convert binary to text?Switch to “binary to text” and paste the 0s and 1s — spaced or not. The tool reads them in groups of eight and turns each byte back into its character.

Does it handle accents and emoji?Yes — it uses UTF-8, so characters beyond basic ASCII are encoded as multiple bytes and decode back correctly.

Is anything uploaded?No — the conversion runs entirely in your browser.
