How it works
Your text is first encoded as a sequence of UTF-8 bytes. Each byte — a value from 0 to 255 — is then written as an 8-digit binary string with leading zeros. So A (byte 65) becomes 01000001, and the emoji 👋 becomes four bytes: 11110000 10011111 10010001 10001011.
Why convert text to binary?
- Teaching how characters and bits relate in computer science courses.
- Creating puzzles and escape-room clues.
- Debugging low-level protocols where you see bit-level data.
- Generating test vectors for bit-manipulation code.
How to use
- Type or paste text into the left panel.
- Pick a separator between bytes (space is most readable).
- Click Encode →. Copy or download.
