Number Base Converter

Number Base Converter makes it simple to convert between binary (base 2), octal (base 8), decimal (base 10), and hexadecimal (base 16) number systems.

Whether you're a computer science student studying number systems, a developer debugging hex values, or preparing for an IT certification exam, this radix converter has you covered.

How It Works

Enter a value in any one of the four base fields, and the other three results update instantly. No buttons to press, no extra steps. Just type and see every conversion at once.

Supported Number Bases

- Binary (Base 2)

- Octal (Base 8)

- Decimal (Base 10)

- Hexadecimal (Base 16)

Key Features

Instant Conversion

Type a number in any base and all other bases are calculated in real time. Converting binary to decimal, hex to octal, or any other combination happens automatically as you type.

Smart Input Validation

The app only accepts valid digits for each base. Binary fields accept 0 and 1 only. Hex fields accept 0-9 and A-F. This prevents errors before they happen.

4-Bit Binary Grouping

Binary results are displayed in 4-bit groups (e.g., 1111 0011) for easy reading. This is especially useful when working with bytes, nibbles, and bitwise operations.

Comma Separator

Large decimal numbers can be displayed with comma separators for readability, making it easy to distinguish between thousands, millions, and beyond.

Clipboard Copy

Tap the copy button next to any result to copy it to your clipboard. Need all four values at once? Use the "Copy All" button to grab every conversion in a single tap.

Dark Mode

Switch between light and dark themes based on your preference. The dark mode is designed to reduce eye strain during late-night study sessions or coding marathons.

Multi-Language Support

Available in 8 languages: English, Korean, Japanese, Indonesian, Hindi, Portuguese (Brazil), Vietnamese, and Thai.
