How are non-ASCII characters handled?

Text is encoded as UTF-8, so accented letters, symbols and emoji are turned into multiple bytes — each still shown as an 8-bit group.

Why is each byte 8 digits long?

A byte is 8 bits, so each byte is padded to 8 binary digits. This keeps the output aligned and easy to split back into bytes.

Is my text sent to a server?

No. The conversion runs entirely in your browser, so nothing you type is uploaded or stored.

How do I convert a letter like A to binary?

The letter A is ASCII code 65, which in 8-bit binary is 01000001. The tool does this for every character automatically.

How many bytes does an emoji become?

Most emoji are four UTF-8 bytes, shown as four 8-bit groups. Some emoji are sequences of several code points and produce even more bytes.

Are the bytes separated by spaces?

Yes. Each 8-bit byte is separated by a single space, which makes it easy to read and to split back into individual bytes when decoding.

Can I reverse this back to text?

Yes — use a binary-to-text converter. Split on spaces, read each group of 8 bits as a byte, and decode the byte sequence as UTF-8.

Text to Binary Converter

Text to binary converter

This converter turns any text into its binary representation, encoding characters as UTF-8 and showing every byte as eight binary digits. It is useful for learning how computers store text, for puzzles and CTF challenges, and for inspecting exactly which bytes a string produces.

How it works

The tool encodes your text as UTF-8, the standard variable-width encoding. Each character becomes one or more bytes: ASCII characters (A–Z, digits, common punctuation) are a single byte, while accented letters, symbols and emoji span two to four bytes. Every byte is converted to base 2 and left-padded to 8 digits, then the bytes are joined with single spaces:

binary = each UTF-8 byte → 8-bit string, space-separated

Example

Hi encodes to two ASCII bytes: H is 72 (01001000) and i is 105 (01101001), giving:

01001000 01101001

Character	Code point	Binary (UTF-8)
A	65	01000001
a	97	01100001
0	48	00110000
space	32	00100000

Everything runs in your browser — nothing you type is uploaded.
