Verified no-login tool
Paste, convert, copy.
Type text to get binary, or paste binary to get text — direction is auto-detected.
The result updates live as you type.
Bytes are shown as space-separated 8-bit groups.
Copy the result with one click.
Built for speed, privacy and reliability — on any device.
Text becomes binary and binary becomes text — detected automatically.
Accents, emoji and other scripts convert correctly, not just ASCII.
Every byte is a clean 8-bit group — readable and copyable.
Conversion runs locally — nothing is sent anywhere.
No account, no limits.
UTF-8 — the web standard. Every character from any language converts correctly, including emoji.
If the input contains only 0s, 1s and spaces it is treated as binary; otherwise as text.
The binary length must be a multiple of 8 — the tool warns you when it is not, and decodes what it can.
No. Conversion runs entirely in your browser.
The tool works in all modern browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, Safari and Opera. We recommend keeping your browser up to date for the best experience.
