Convert text to binary or hexadecimal, or decode binary and hex back to text. Runs entirely in your browser.
Convert text to its binary or hexadecimal representation, or decode binary / hex back to text. Runs in the page.
What the text / binary / hex converter does
Convert a string to its 8-bit binary or 2-digit hexadecimal form, or take binary and hex groups and turn them back into text. It is useful for teaching, debugging encodings, or inspecting how characters are stored.
Frequently asked questions
What encoding is used?
Each character’s Unicode code point is shown as 8-bit binary or 2-digit hex, which matches UTF-8 for basic Latin text.
How should I paste binary or hex?
Separate each group with a space, just as the encoder produces them, and pick the matching decode mode.
Is anything uploaded?
No. Conversion runs in the page.
How to use it
- Open the tool and locate the input field at the top of the page.
- Type or paste your text into the input box, or enter binary groups (like “01000001”) or hex groups (like “41”).
- Select one of the four mode options: “Text to binary” for 8-bit output, “Text to hex” for two-digit hex codes, “Binary to text” to decode binary input, or “Hex to text” to decode hex input.
- Watch the result appear below the input field as you type — no button press needed.
Where it comes in handy
A programmer debugging a network packet sees “48 65 6C 6C 6F” and needs to verify it spells “Hello” — this tool converts the hex group back to readable text instantly.
A student learning computer architecture traces the byte “01000001” through memory and uses the converter to confirm it represents the ASCII character “A” with no ambiguity.
A data analyst inspecting a CSV file with encoding errors pastes “31 32 33” into the hex-to-text mode and discovers the corrupted cells actually contain the string “123” instead of numeric values.
Worth knowing
- Unicode code points above 255 (like emojis or accented characters) require more than 8 bits — this tool shows only the first byte, which may produce incomplete results for non-Latin text.
- Binary or hex input must be space-separated groups; a continuous string like “01000001” without spaces will fail to decode because the tool cannot determine where each byte begins.
- Empty input returns an empty result — the converter does not display placeholders or error messages, so missing output means either invalid format or a whitespace-only entry.
Common conversions reference
| Input | Binary output | Hex output |
|---|---|---|
| “A” | 01000001 | 41 |
| “Hi” | 01001000 01101001 | 48 69 |
| “!” | 00100001 | 21 |
| “123” | 00110001 00110010 00110011 | 31 32 33 |
| “test” | 01110100 01100101 01110011 01110100 | 74 65 73 74 |
| “Hello” | 01001000 01100101 01101100 01101100 01101111 | 48 65 6C 6C 6F |
Rounding does not apply here because each character maps to an exact byte value — binary and hex are discrete representations with no fractional parts to truncate.
