Binary Text Converter
Convert plain text to binary or binary back to text.
Binary — the language of ones and zeros — is how every computer stores and processes data at the hardware level. This converter translates readable text to its binary representation and converts binary sequences back to human-readable characters, useful for learning, programming exercises, and data analysis.

How to Convert Between Binary and Text
- Enter binary or text — paste binary digits (e.g., 01001000 01101001) or type plain text.
- Select conversion direction — choose binary-to-text or text-to-binary.
- Click Convert — the tool processes each 8-bit group (byte) and produces the result.
- Copy the output — use it for learning, programming exercises, or data encoding.
Frequently Asked Questions
How does binary-to-text conversion work? ▼
Each character is represented by 8 binary digits (bits), called a byte. The binary value is converted to a decimal number, which maps to an ASCII/Unicode character. For example, 01001000 = 72 in decimal = "H", and 01101001 = 105 = "i". Together, "01001000 01101001" = "Hi".
Why is binary important in computing? ▼
Computers operate using electrical signals that have two states: on (1) and off (0). Binary is the fundamental language of all digital systems — every file, image, video, and program is ultimately stored and processed as sequences of binary digits.
What is a byte? ▼
A byte is 8 bits — the standard unit for representing a character in ASCII. One byte can represent 256 different values (0–255). Text files use one or more bytes per character. This tool groups binary input into 8-bit bytes for conversion.
Can I convert non-English text to binary? ▼
Non-English characters that fall within ASCII (codes 0–127) work directly. Characters outside ASCII (like accented letters, CJK characters, or emojis) use multi-byte UTF-8 encoding and produce longer binary sequences per character.
What is the difference between binary and hexadecimal? ▼
Both are number systems. Binary uses base-2 (digits 0–1), while hexadecimal uses base-16 (digits 0–9, A–F). Each hex digit represents exactly 4 binary digits, making hex a more compact way to write binary: 01001000 in binary = 48 in hex.
Is my data stored? ▼
No. All conversions run in your browser. Nothing is sent to any server.
