About This Tool
Decode space-separated binary bytes back into readable ASCII text. Paste binary output from serial logs, network captures, or encoding exercises and instantly see the original characters. Each 8-bit group is interpreted as one ASCII character code (0–127). This tool is the reverse of ASCII-to-binary encoding — essential for CTF challenges, UART debugging, and understanding how text is stored in computer memory at the bit level.
Worked Examples
Input: 01001000 01101001 → Output: Hi
01001000=72=H, 01101001=105=i
Input: 01000001 01000010 01000011 → Output: ABC
65=A, 66=B, 67=C — consecutive uppercase letters
Input: 00110001 00110000 00110000 → Output: 100
49="1", 48="0", 48="0" — digit characters, not the number
