What encoding is used for the text?

The tool uses the character's UTF-16 code point (which equals the ASCII value for standard ASCII characters 0–127). For best results use standard ASCII text; extended Unicode characters will show their code point values.

Why are binary groups 8 bits wide?

8 bits (one byte) is the standard unit for ASCII characters. Each character is zero-padded to 8 bits so the output aligns neatly and is easy to read.

Can I convert binary back to text?

Yes. Each tab works in both directions. Enter binary digits (separated by spaces) and the tool converts them back to readable text.

What base does hexadecimal use?

Hexadecimal (hex) is base 16, using digits 0–9 and letters A–F. It is widely used in programming to represent bytes compactly — one byte is exactly two hex digits.

About this tool

Type any text and instantly see its binary (8-bit), hexadecimal, octal, or decimal (ASCII code) representation. Switch between four direction tabs: Text → Binary, Text → Hex, Text → Octal, and Text → Decimal. A character-by-character breakdown table shows each letter alongside its code in the selected base. All conversion is real-time as you type, and a copy button lets you grab the output instantly.

How to use

1 Select a conversion tab: Binary, Hexadecimal, Octal, or Decimal.
2 Type or paste text in the input area to see the encoded output instantly.
3 Or paste encoded values in the output area to decode back to text.
4 Use the Copy button to copy the result, and the breakdown table for per-character details.
