ASCII in Binär Converter

Each character is mapped to its ASCII decimal number (0–127), which is then converted into an 8-bit binary representation by finding its base-2 powers. For example, the letter 'H' has an ASCII value of 72. In base-2 binary, 72 is 01001000₂ (64 + 8). The lowercase letter 'i' has an ASCII value of 105, which is 01101001₂ (64 + 32 + 8 + 1). Together, 'Hi' becomes 01001000 01101001.

Original standard ASCII is a 7-bit character encoding defining 128 characters (0 to 127). Modern computers store data in 8-bit bytes (octets), so the Most Significant Bit (MSB, the 8th bit) is padded with a leading zero (e.g. 01000001 for 'A'). Our converter allows you to select between standard 8-bit padded bytes, pure 7-bit bitstrings, or 16-bit wide formats.

Standard ASCII characters (0–127) occupy exactly 1 byte starting with 0xxxxxxx. Non-ASCII characters (such as accented letters, Cyrillic, Greek, or emojis) use 2 to 4 variable bytes in UTF-8. For example, the Euro symbol '€' is encoded in UTF-8 as 3 binary bytes: 11100010 10000010 10101100.

You can format your binary output with standard Space (01001000 01101001), Comma, Comma + Space, 0b Prefixes (0b01001000 0b01101001), 4-bit Nibble Spacing (0100 1000 0110 1001), JSON Array, C/C++ Array Literals, continuous unspaced bitstreams, or any custom delimiter.

Bit parity is a simple error-detection technique used in telecommunications and hardware protocols. If the count of '1' bits in an 8-bit byte is even, it has Even Parity; if odd, it has Odd Parity. Our character breakdown table calculates the exact parity and 1s/0s count for every character in your payload.
