See How Computers Store Your Words
Every message you type, every web page you read and every file you save is stored as a long sequence of 0s and 1s. This tool shows you exactly what that looks like. Type any text — in English, Hindi or with emojis — and it is instantly converted to binary code, one 8-bit byte at a time. It is a great way for students to understand how computers represent information, and a fun way to create binary messages.
How to Use the Text to Binary Converter
- Type or paste text into the Plain Text Input box.
- The binary appears instantly, with a space between each byte.
- Copy the binary code with one click.
Example
| Character | Decimal (byte value) | Binary |
|---|---|---|
| H | 72 | 01001000 |
| i | 105 | 01101001 |
| (space) | 32 | 00100000 |
| A | 65 | 01000001 |
So “Hi” becomes 01001000 01101001.
How Binary Numbers Work
In the decimal system each position is worth ten times the one to its right (1, 10, 100…). In binary, each position is worth twice the one to its right:
| 128 | 64 | 32 | 16 | 8 | 4 | 2 | 1 |
|---|---|---|---|---|---|---|---|
| 0 | 1 | 0 | 0 | 1 | 0 | 0 | 0 |
Add up the positions with a 1: 64 + 8 = 72, which is the code for “H”. One byte can hold any value from 0 (00000000) to 255 (11111111).
From Characters to Bytes: ASCII and UTF-8
To turn letters into numbers, computers use a character encoding. The original standard, ASCII, assigned numbers 0–127 to English letters, digits and punctuation. That was not enough for the world’s languages, so Unicode was created to give every character a unique number, and UTF-8 is the way those numbers are stored as bytes.
- English letters and digits: 1 byte each (identical to ASCII).
- Hindi, Bengali, Tamil and other Indian scripts: usually 3 bytes per character.
- Most emojis: 4 bytes.
For example, the Hindi letter “क” is stored as three bytes: 11100000 10100100 10010101. This tool uses UTF-8, the same encoding used by the vast majority of websites.
Fun and Practical Uses
- Computer science homework on number systems and encoding.
- Puzzles and treasure hunts with binary clues.
- Geeky gifts — a name in binary on a card or bracelet.
- Understanding file sizes — seeing why a Hindi message uses more storage than the same length in English.
