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.

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.

Dark Mode
Switch between light and dark themes based on your preference.

Multi-Language Support
Available in 20 languages.
