Working with binary, hex, or octal numbers? I built a converter that shows all four representations simultaneously and visualizes the bits.
What it does
- Type in any base (decimal, binary, hex, octal) and see all others update live
- Bit visualization — see each bit as 0 or 1 with position labels
- Copy any value with one click
- Reference table with common values (max byte, ASCII characters, powers of 2)
Quick Reference
| Decimal | Binary | Hex | Notes |
|---|---|---|---|
| 0 | 0 | 0 | Zero |
| 127 | 1111111 | 7F | Max signed byte |
| 255 | 11111111 | FF | Max byte |
| 256 | 100000000 | 100 | Byte overflow |
| 1024 | 10000000000 | 400 | 1 KB |
| 65535 | 1111111111111111 | FFFF | Max 16-bit |
