Text to Binary Online

Updated 2026-07-09

Convert text to binary online for free. Type any string and SnapTools shows its UTF-8 bytes as 8-bit binary groups, character by character — spaces between bytes for readability, ready to copy or download. Everything runs in your browser, so your text is never uploaded.

Binary is how every character is ultimately stored, and seeing it spelled out is useful for teaching, puzzles, or low-level debugging. Because the text is encoded as UTF-8 first, you can see exactly why an emoji or accented letter takes more than eight bits — and turn it back into text any time with Binary to Text.

// how to use

  1. 1 Type or paste text into the input panel on the left.
  2. 2 SnapTools converts each character to 8-bit binary (its UTF-8 bytes) as you type.
  3. 3 Copy or download the binary output, or switch to Binary to Text to reverse it.

// faq

No. The conversion runs entirely in your browser, so your text never leaves your machine.
Text is encoded as UTF-8, then each byte is shown as eight binary digits. Characters outside ASCII expand to two or more bytes.
A byte is eight bits, so each UTF-8 byte becomes an 8-digit binary group. Bytes are separated by spaces so the groups stay readable.
Yes. The Binary to Text tool reads 8-bit groups (ignoring spaces and separators) and decodes them back to readable text.
Yes. Because it encodes as UTF-8 first, multi-byte characters produce several 8-bit groups, and Binary to Text reassembles them correctly.
