0️⃣ Text to Binary Converter

About this Text to Binary Converter

Computers store every letter as a number, and every number as binary — a string of 0s and 1s. This converter turns your text into UTF-8 bytes shown as 8-bit binary groups, and decodes binary back into readable text. It is a fun, hands-on way to see how encoding works under the hood.

How to use it

1. Type plain text and click Text → Binary to encode it.
2. Or paste binary code (spaces optional) and click Binary → Text to decode it.
3. Read the result in the box below.
4. Copy the result to share a secret message with a friend.

Example

The word 'Hi' becomes 01001000 01101001 — H is byte 72 and i is byte 105 in UTF-8.

Frequently asked questions

Why does one letter sometimes make several binary groups?

Characters outside plain English, like emoji or accented letters, take 2–4 UTF-8 bytes each, so they produce several 8-bit groups.

Do the spaces between groups matter?

No. The decoder ignores spaces and line breaks and simply reads the 0s and 1s in order, eight at a time.
