This tool converts text to binary, hexadecimal, decimal, or octal, and decodes in the other direction too. Everything runs in your browser, so your data stays on your device.
- Select a mode. Choose "Text to Binary" to encode readable text into a code format, or "Binary to Text" to decode encoded data back into readable characters.
- Pick a format. Choose Binary (base 2), Hexadecimal (base 16), Decimal (base 10), or Octal (base 8). The output updates instantly when you switch formats.
- Enter your input. Type or paste your text (or encoded data) into the input box. The translated output appears in real time as you type.
- Copy or share. Click Copy to send the result to your clipboard, or Share to generate a link that pre-fills the tool with your current input.
About Binary Translation
Computers store all data as binary, sequences of 0s and 1s. Each character you type is assigned a numeric code (its ASCII or Unicode value), and that number can be expressed in different bases. Binary uses base 2, hexadecimal uses base 16, decimal uses base 10, and octal uses base 8.
For example, the letter "H" has an ASCII code of 72. In binary that is 01001000, in hex it is 48, and in octal it is 110. This tool handles the conversion automatically for every character in your input, letting you move between human-readable text and its numeric representation in any of these four bases.
Binary translation is useful for debugging network protocols, understanding character encoding, learning computer science fundamentals, and working with low-level data formats.
Frequently Asked Questions
How does binary translation work?
Every text character has a numeric code in the ASCII or Unicode standard. Binary translation converts that numeric code into a different base. For binary, each character becomes 8 bits (for example, "A" is 01000001). For hex, each character becomes two hex digits (for example, "A" is 41). This tool encodes each character individually and separates the values with spaces so you can read them clearly.
What formats are supported?
This tool supports four formats: Binary (base 2, using only 0 and 1), Hexadecimal (base 16, using 0-9 and A-F), Decimal (base 10, standard numbers), and Octal (base 8, using digits 0-7). You can encode text into any of these formats and decode back to text from any of them.
Can I convert binary back to text?
Yes. Switch the mode to "Binary to Text," select the format that matches your encoded data, and paste it into the input box. The tool accepts space-separated values or (for binary) continuous strings of 0s and 1s in 8-bit groups. The decoded text appears instantly in the output.
Does this support Unicode?
This tool works with the character code of each input character. Standard ASCII characters (letters, digits, punctuation) convert perfectly in all four formats. Characters outside the basic ASCII range (such as accented letters or emoji) use their Unicode code point value, which may be larger than one byte. For full multi-byte Unicode support, consider using the Base64 encoder, which handles UTF-8 encoding natively.
