Convert 8-bit binary (space-separated) back to readable text in one click. Each 8-digit binary group becomes the character it represents in ASCII or basic UTF-8.
Reversing binary back to text is the standard operation paired with text-to-binary. It's used to decode messages from puzzles, debug data parsers, verify binary representation in educational contexts, and decrypt simple cipher exercises that use binary as their notation.
Paste binary (each character as 8 bits, separated by spaces) into the textarea and click. The tool splits on whitespace, parses each 8-bit chunk as a base-2 integer, and converts each to its character via String.fromCharCode(). The result is the decoded text.
Use it when decoding binary messages from puzzles, when reverse-engineering simple character encodings, when verifying that text-to-binary conversion was correct, when teaching encoding concepts, or when debugging data export formats that use binary notation.
The input must be space-separated 8-bit groups — no commas, no other delimiters. For binary that's not space-separated, manually insert spaces every 8 digits first. For mixed binary+hex+base64, use the Binary Decoder tool which auto-detects the format.
Insert spaces every 8 characters first — most text editors have a regex find-replace that can do this.
Partially — basic Latin characters work. For full UTF-8 use a TextDecoder-based tool.
Those binary values map to non-printable control characters. The character was decoded correctly but doesn't display.
