Binary to ASCII Converter

What This Binary-to-ASCII Page Decodes

ASCII assigns values 0 through 127 to letters, digits, punctuation, and control characters. On this page, write each value as an 8-bit byte so the character boundary is explicit. A true ASCII byte always begins with 0, because values above 01111111 are outside the 7-bit ASCII range.

Worked Example: Binary to ABC

Split the input into bytes, then read each byte as an ASCII value:

So 01000001 01000010 01000011 becomes ABC.

Input Rules and Edge Cases

• Whitespace between bytes is optional, but the total number of bits must still be a multiple of 8.
• Bytes from 00000000 through 01111111 are ASCII. Values from 10000000 through 11111111 are not standalone ASCII characters.
• ASCII includes non-printing control values such as tab (9), line feed (10), and carriage return (13). A decoded result can therefore contain invisible characters.
• If your data represents multilingual text or emoji, use a UTF-8-aware decoder instead of treating every byte as an independent ASCII character.

ASCII vs Binary-to-Text

Use this page when the question is specifically about ASCII byte values. For general text encoded as UTF-8, use the Binary to Text converter. For a complete code reference, see the ASCII table and the guide to ASCII, Unicode, and UTF-8.
