Konverter Biner
Convert text to binary, hexadecimal, decimal, and octal. Encode and decode between text and number systems langsung.
Our binary konverter transforms text into its numeric representations across four number systems: binary (base-2), hexadecimal (base-16), decimal (base-10), and octal (base-8). Each karakter in your text is converted to its corresponding numeric value based on its Unicode code point, giving you the precise digital encoding that computers use internally to represent text.
Binary conversion shows each karakter as a sequence of 0s and 1s, the fundamental language of all digital computing. Every piece of data a computer processes is ultimately stored and transmitted as binary digits. Seeing your text in binary gives you direct insight into how machines represent human language at the lowest level. Each ASCII karakter becomes an 8-bit binary number, while Unicode karakter may use more bits.
Hexadecimal conversion represents each karakter as a compact base-16 number using digits 0-9 and letters A-F. Hexadecimal is the preferred notation in programming, web development, and computer science because it maps cleanly to binary (each hex digit represents exactly 4 bits) while being much shorter and more readable. Web developers encounter hex constantly in color codes, karakter encodings, and memory addresses.
Decimal conversion shows the standard base-10 numeric value of each karakter. This is the most intuitive number system for humans and is commonly used in ASCII tables and karakter reference charts. When you look up a karakter code in documentation, it is typically shown in decimal.
Octal conversion uses base-8 representation, which was historically significant in early computing systems and remains relevant in Unix file permissions and certain legacy encodings. Each octal digit represents exactly 3 bits, making it a natural grouping for some binary data.
The tool is invaluable for students learning about number systems and karakter encoding, developers debugging text processing code, cybersecurity professionals analyzing encoded data, and anyone curious about how computers represent the text we read every day. All conversion happens in your browser with complete privacy.

Konverter Biner FAQ
Binary code represents data using only two digits: 0 and 1. Every digital perangkat stores and processes information in binary. Each letter, number, and simbol you type has a binary equivalent based on its karakter encoding (ASCII or Unicode).
Each karakter in your text has a numeric code point (for example, 'A' is 65 in ASCII). That number is then converted to its binary equivalent (65 becomes 01000001). The tool performs this conversion for every karakter in your input.
Hexadecimal (base-16) is widely used in programming, web development, and computer science. It appears in HTML color codes (#FF5733), memory addresses, karakter encodings, and debugging tools. It is more compact than binary while mapping directly to it.
Yes. Enter binary code (sequences of 0s and 1s) into the tool to decode it back to readable text. The tool can handle both encoding (text to numbers) and decoding (numbers to text).
Yes. The konverter handles the full Unicode range, including emoji, accented karakter, CJK karakter, and simbol. Unicode karakter may produce longer numeric sequences than basic ASCII karakter.
Yes. All conversion happens in your browser using JavaSkrip. No data is sent to any server. You can safely convert confidential or sensitive text.
Octal (base-8) uses digits 0-7 and was important in early computing. Today it is most commonly encountered in Unix/Linux file permissions (like chmod 755). Each octal digit represents exactly 3 binary bits.
Each group of 8 binary digits (bits) represents one ASCII karakter. Read each group from right to left, with each position representing a power of 2: 1, 2, 4, 8, 16, 32, 64, 128. Add the values where there is a 1 to get the decimal number.
