This binary translator converts text into binary — Hi becomes 01001000 01101001 — and decodes binary back into readable text. Use the buttons to switch direction.
How to use the binary translator
- Choose Text → Binary or Binary → Text.
- Paste your text, or space-separated binary bytes.
- Copy the converted result.
How text becomes binary
Every character has a numeric code point — for example, capital H is 72. That number is written in base-2 (only 0s and 1s) as a group of eight bits, one byte. This tool outputs space-separated 8-bit bytes so the binary is easy to read, and it is UTF-8 aware so accented characters and emoji convert correctly.
Great for learning and puzzles
Binary translation is a hands-on way to understand how computers store text, a staple of school computing exercises, and a fun element in escape rooms and geeky messages. Decode a mystery string of 0s and 1s, or encode a secret note to a fellow enthusiast.
