Paste your binary code into the input box and get the corresponding ASCII text back immediately. Enter space-separated 8-bit binary groups like 01001000 01101001 and the converter decodes each byte into its readable character. Supports standard ASCII/UTF-8 encoding for all printable characters.

To convert binary to ASCII, split your binary string into 8-bit groups (bytes). Convert each 8-bit group from base-2 to a decimal number, then look up that decimal value in the ASCII table to find the corresponding character. For example, 01000001 in binary equals 65 in decimal, which is the letter 'A' in ASCII.
The binary value 01000001 converts to the decimal number 65, which represents the uppercase letter 'A' in the ASCII character table. You can verify this by calculating: 2^6 + 2^0 = 64 + 1 = 65.
The binary value 00110000 converts to decimal 48, which is the character '0' (zero digit) in ASCII. This shows that ASCII digits start at decimal 48 — '0' through '9' are represented by binary values 00110000 through 00111001.
Simply paste your binary code into the input box with each 8-bit byte separated by spaces (e.g. 01001000 01100101 01101100 01101100 01101111). Select your encoding and delimiter options, then the tool automatically decodes every byte and displays the resulting ASCII text along with a full character-by-character breakdown table.
ASCII uses exactly 1 byte (8 bits) to represent each character and covers 128 standard characters (letters, digits, punctuation). UTF-8 is a superset of ASCII — for the first 128 characters it uses the same single-byte encoding, but it can use up to 4 bytes for characters beyond the standard ASCII range, such as accented letters or emoji.
Standard ASCII encoding uses 8 bits (1 byte) to represent each character. Each group of 8 binary digits maps to one specific decimal value between 0 and 255, which in turn corresponds to one ASCII character. If your binary string isn't a multiple of 8 bits, the converter may not decode it correctly.
Yes — select 'No Delimiter (continuous)' from the delimiter option. The converter will automatically split your continuous binary string into 8-bit chunks from left to right. For example, 0100100001101001 will be split into 01001000 and 01101001, which decode to 'H' and 'i'.
Standard ASCII covers 128 characters (decimal 0–127), including uppercase letters A–Z (65–90), lowercase letters a–z (97–122), digits 0–9 (48–57), common punctuation, and control characters. Extended ASCII covers 256 characters (0–255) and adds additional symbols and accented characters.
