Binary Translator 2026 — Text ↔ Binary Code Converter

Convert text to binary and binary back to text instantly, plus decimal, hexadecimal and octal in both directions. Text is encoded as UTF-8, so accented letters, non-Latin scripts and emoji all convert correctly. Every conversion runs in your browser — nothing is uploaded.

Frequently Asked Questions

What is a binary translator?

A binary translator converts text, numbers, or other data into binary code (sequences of 0s and 1s) and vice versa. This tool supports text ↔ binary, decimal ↔ binary, hex ↔ binary, and octal ↔ binary conversions, with a step-by-step character breakdown table.

What does 01001000 01100101 01101100 01101100 01101111 mean?

That is 'Hello' in binary. Each 8-bit group is one character: 01001000 = H (72), 01100101 = e (101), 01101100 = l (108), 01101100 = l (108), 01101111 = o (111). Together they spell Hello.

What is 'A' in binary?

The uppercase letter 'A' has an ASCII decimal value of 65, which is 01000001 in 8-bit binary. Lowercase 'a' is ASCII 97 = 01100001 in binary. You can click 'A' in the Quick Examples section to see the full breakdown.

What is 'I Love You' in binary?

I Love You in binary is: 01001001 00100000 01001100 01101111 01110110 01100101 00100000 01011001 01101111 01110101. Each 8-bit group is one character. Spaces are 00100000 (32 in ASCII).

What is 'Hello World' in binary?

Hello World in binary is: 01001000 01100101 01101100 01101100 01101111 00100000 01010111 01101111 01110010 01101100 01100100. That is 11 characters including the space (00100000 = ASCII 32).

What is a bit vs a byte?

A bit is a single binary digit — either 0 or 1. A byte is a group of 8 bits. In ASCII text encoding, one character equals one byte (8 bits). So 'Hello' = 5 characters = 5 bytes = 40 bits.

Why do computers use binary?

Computers use binary because their transistors — billions of tiny on/off switches — have exactly two states: on (1) and off (0). All data, programs, and instructions are represented as patterns of these two states. Binary maps perfectly to the physics of electronic hardware.

What is ASCII?

ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns a number to 128 characters — letters, digits, punctuation, and control characters. For example: 'A' = 65, 'a' = 97, '0' = 48, space = 32. Binary translators use ASCII to convert text to binary.

What is hexadecimal and how does it relate to binary?

Hexadecimal (base 16) uses digits 0–9 and letters A–F. Every 4 bits map to exactly one hex digit — for example, 1111 = F, so 11111111 = FF. Programmers prefer hex because it's much shorter than binary while still mapping directly to binary values.

What is octal and how does it relate to binary?

Octal (base 8) uses digits 0–7. Every 3 bits map to one octal digit — for example, 111 = 7, 000 = 0. Octal was widely used in early computing (Unix file permissions still use octal today, e.g. chmod 755). Our Binary Translator includes a dedicated Octal ↔ Binary conversion mode.

Can binary represent all characters including emoji?

Yes. This tool encodes text as UTF-8, the standard the web uses, so accented letters, non-Latin scripts and emoji all convert correctly. ASCII characters take one byte (8 bits); é takes two, most CJK characters three, and emoji four — so one emoji is four 8-bit groups, not one.

Is this binary translator free?

Yes, 100% free — no sign-up, no login, and no limits. Translate text, decimal, hex, and octal to binary and back. Download your results as a .txt file or upload a text file to convert it instantly.
