How text becomes binary
Computers store text as numbers, and each number is a string of bits. This tool encodes your text to UTF-8 bytes and shows each byte as eight 0s and 1s. Decoding reverses it: paste space-separated binary bytes and get the original text back, including emoji and accented characters.
Private by design. Conversion runs in your browser; nothing is uploaded.
Frequently asked questions
What format is the binary in?
Eight bits per byte, separated by spaces. Each character may be one or more bytes depending on its UTF-8 encoding.
Does it support emoji and accents?
Yes. Text is encoded as UTF-8 first, so all Unicode characters round-trip correctly.
Is my text uploaded?
No. Everything is processed locally in your browser.
