Turn any text into its binary representation, one 8-bit group per byte. Type or paste a message and the tool shows the exact bits a computer stores for it. Useful for teaching how characters map to bytes, debugging encoding issues, or building puzzles.
How this is calculated
Each character is encoded to UTF-8 bytes, and every byte is written as an 8-digit base-2 number, zero-padded on the left. Groups are separated by a single space. This matches the standard UTF-8 byte encoding, so multi-byte characters produce more than one group.
How to use
- Type or paste the text you want to convert.
- Read the binary output, with one 8-bit group per UTF-8 byte.
- Copy the result to use elsewhere.
Examples
- Two letters:
"Hi" becomes 01001000 01101001 - Accented letter:
"é" becomes 11000011 10101001 (two UTF-8 bytes)
FAQ
- How are non-English characters handled?
- Every character is encoded as UTF-8 first. Characters outside the basic ASCII range use two or more bytes, so they produce more than one 8-bit group.
- Why is each group 8 bits?
- A byte is 8 bits, and UTF-8 stores text as a sequence of bytes. Padding each byte to 8 digits keeps the output aligned and unambiguous.
- Does this run on a server?
- No. The conversion happens in your browser, so the text you enter never leaves your device.
