A binary translator converts text into the 1s and 0s computers actually store, and back again. Useful for CS homework, debugging encoding issues, secret messages, or just understanding how text becomes data.
This guide covers ASCII vs. UTF-8, the conversion process, and common gotchas with multi-byte characters.

Convert text to binary and back instantly. ASCII and UTF-8 supported.
How Text Becomes Binary
Every character has a numeric code point. ASCII covers the first 128 codes (English letters, digits, punctuation); UTF-8 extends this to every script in the world.
The conversion is two steps:
- Character → number using the encoding table (e.g., 'A' = 65).
- Number → binary as a fixed-width string (typically 8 bits per byte).
Example: 'A' → 65 → 01000001.
ASCII vs. UTF-8
| Encoding | Range | Bytes per char |
|---|---|---|
| ASCII | 0-127 (English only) | 1 |
| UTF-8 (Latin) | 0-127 | 1 |
| UTF-8 (Latin-ext, Greek, Cyrillic) | 128-2047 | 2 |
| UTF-8 (most scripts) | 2048-65535 | 3 |
| UTF-8 (emoji, rare scripts) | 65536+ | 4 |
Translating "Hello" gives 5 bytes. Translating "नमस्ते" gives 18 bytes. Translating "👋" gives 4 bytes.
Common Binary Codes (ASCII)
| Char | Decimal | Binary |
|---|---|---|
| A | 65 | 01000001 |
| Z | 90 | 01011010 |
| a | 97 | 01100001 |
| z | 122 | 01111010 |
| 0 | 48 | 00110000 |
| 9 | 57 | 00111001 |
| space | 32 | 00100000 |
| ! | 33 | 00100001 |
When You Actually Need This
- CS homework — Number systems, encoding chapters.
- Debugging — Inspecting raw bytes when text looks corrupted.
- Embedded systems — Sending characters over a serial line.
- CTF challenges — Many puzzles encode flags in binary.
- Crypto education — Understanding ciphers that operate on bits.
Common Gotchas
- Spaces between bytes — Most translators expect "01000001 01000010" not "0100000101000010".
- Leading zeros matter — Use 8 bits per byte; "1" is not the same as "00000001".
- Multi-byte chars — Emoji and non-Latin scripts produce multiple bytes; don't assume 1 char = 8 bits.
- Newlines — Encoded as 00001010 (LF) or 00001101 00001010 (CRLF). Hidden in some inputs.

Frequently Asked Questions
Why does my Hindi text produce so many bytes?+−
Devanagari characters are 3 bytes each in UTF-8 because they fall outside the ASCII range.
Can I convert binary back to text?+−
Yes — just paste 8-bit chunks separated by spaces and pick "Binary to Text".
What if my binary string has odd length?+−
It will fail to decode. Each character must be exactly 8 bits (or 16/24/32 for UTF-8 multi-byte sequences).
Is ASCII the same as binary?+−
No — ASCII is the mapping from characters to numbers; binary is just the base-2 representation of those numbers.
Can binary represent emoji?+−
Yes, with UTF-8 encoding. Most emoji require 4 bytes (32 bits).
