How to convert binary to text

Split the binary code into 8-bit groups (bytes).
Convert each byte to its decimal value.
Look up the UTF-8 character for each value — that's your text.

Example: 01001000 01101001 → 72 105 → "Hi".

Background reading: the ASCII standard on Wikipedia.

Binary to text in code

Python

bytes(int(b, 2) for b in "01001000 01101001".split()).decode()
# → 'Hi'

JavaScript

"01001000 01101001".split(" ")
  .map(b => String.fromCharCode(parseInt(b, 2))).join("");
// → 'Hi'

C

#include <stdio.h>
#include <stdlib.h>

int main(void) {
    const char *s = "01001000";
    printf("%c\n", (char)strtol(s, NULL, 2));  /* → H */
    return 0;
}

Real-world applications

Decoding binary dumps back into readable messages.
Checking what a program actually received over a byte-level protocol.
Recovering text from QR codes and barcodes that store raw bytes.
Classroom demos of how computers turn stored bits back into letters.

Common mistakes

Splitting the bits into the wrong group size — text bytes are 8 bits each.
Forgetting that UTF-8 characters can span multiple bytes — splitting mid-character gives �.
Including stray spaces inside a byte group, which shifts every byte after it.

Common values

01000001 = A (65)
01100001 = a (97)
00100000 = space (32)
00110000 = 0 (48)
01011010 = Z (90)
00100001 = ! (33)

Key takeaways

Split the bits into groups of 8, then convert each byte to its character.
01000001₂ = 65 = ‘A’.
Input must be valid UTF-8 or the output will look garbled.
Multi-byte sequences (emoji, non-Latin scripts) must be pasted whole.

Frequently asked questions

How do I convert binary to text?

Split the binary into 8-bit bytes, convert each to decimal, then to its character. The converter above does it instantly.

What text is 01001000 01101001?

01001000 01101001 in binary is “Hi”.

Can I paste binary without spaces?

Yes — the converter also accepts continuous binary and splits it into 8-bit groups automatically.

Why do I see � in the output?

That replacement character appears when bytes are split mid-character or the binary is not valid UTF-8 — check the grouping.

What binary is the letter A?

A is byte 65, which is 01000001 in binary.

What does 01000001 mean?

01000001 = 65 = the letter ‘A’.

Why do I see strange characters in the output?

The input probably is not valid UTF-8 — check that the bits are grouped in 8s and form real character codes.

Can binary represent emoji?

Yes — emoji are multi-byte UTF-8 sequences; paste the full 32-bit sequence to decode one.
