Binary Translator
Translate between Text, Binary, Hex and Decimal instantly in your browser. Professional options, live validation, copy/download, and total privacy — everything runs client-side.
Professional Binary Translator — Fast, Accurate, Private
MyToolMaster’s Binary Translator helps developers, students, QA engineers, and cybersecurity professionals convert data between human-readable text and machine-friendly formats such as binary, hexadecimal, and decimal. The app runs entirely in your browser, so sensitive payloads, credentials, or exam files never leave your device. With sensible defaults, flexible delimiters, and live validation, it delivers consistent, predictable results for everyday development and learning tasks.
How to Use This Tool
- Pick a mode. Use the tabs for Text → Binary, Binary → Text, Text → Hex, Hex → Binary, or Binary → Decimal. Auto-Detect guesses the format based on input.
- Paste or type your input. For binary, you can use spaces, commas, pipes, or no delimiter. Hex can be spaced or continuous.
- Adjust options. Choose bit length (7/8/16), delimiter style, grouping (4 or 8), and charset (UTF-8 or Latin-1). Grouping only affects formatting; it won’t change the meaning of the bytes.
- Convert. Click Convert (or press Ctrl/Cmd + Enter). The output appears on the right with size indicators.
- Copy or Download. Use Copy to send the result to your clipboard or Download to save a `.txt` file with a timestamped name.
- Swap directions. Click Swap to move the output back into the input and reverse the mode automatically.
- Validate quickly. If the input includes invalid characters (e.g., non-0/1 in binary), the status bar highlights the error and points to the first offending index.
Common workflows: debugging binary payloads, preparing CTF challenges, verifying protocol frames, explaining encodings to students, and converting small text snippets to inline formats for configuration files. For large files, consider scripting with Node.js or Python, then confirm a few samples here.
Best Practices
- Use UTF-8 for international text. UTF-8 is the web standard; Latin-1 is useful for legacy systems.
- Prefer spaces as delimiters. They’re easy to read and paste into terminals. Use “none” when compactness is critical.
- Remember size growth. Binary and hex strings expand data size versus bytes on disk; don’t store long messages in binary unless required.
- Group visually. 8-bit grouping maps cleanly to bytes; 4-bit grouping is useful when thinking in nibbles or hex.
FAQ — Binary Translator
What encodings are supported?
The translator supports UTF-8 and Latin-1 (ISO-8859-1) for text. Binary conversions operate on byte values; for multi-byte characters in UTF-8, you’ll see multiple 8-bit groups per character.
How does Auto-Detect work?
It inspects your input: if it contains only 0/1 and delimiters, it treats it as binary; if it’s valid hex digits with optional spaces, it’s hex; otherwise it assumes text. You can always override by choosing a specific mode.
Why do I see more bits for some characters?
Non-ASCII characters (like emojis or accented letters) require multiple bytes in UTF-8. Each byte becomes an 8-bit group, so the output grows accordingly.
Is my data uploaded?
No. All conversion happens locally in your browser using JavaScript. Nothing is sent to a server.
Can I paste binary without spaces?
Yes. Choose “None” for delimiter and the tool will still parse; grouping controls only affect output formatting.
Do you support decimal and hexadecimal conversions?
Yes. Use Text ⇄ Hex for textual data, Hex ⇄ Binary for bit-level inspection, and Binary → Decimal to quickly get numeric values for registers or flags.
What’s the difference between 7-bit and 8-bit modes?
7-bit is historical (ASCII), whereas 8-bit corresponds to modern byte-addressable systems. Most users should leave it at 8-bit.
Why is my pasted hex rejected?
Ensure it contains only 0–9 and A–F (case-insensitive). Optional delimiters like spaces or commas are fine. Prefixes like 0x are ignored.
Can I use the result in code?
Absolutely. Binary strings are great for teaching and docs; for code, hex or byte arrays are usually more compact. Use Copy/Download to move results into your IDE.
