Number Base Converter — Bin / Oct / Dec / Hex + Bitwise

Introduction

Paste a value in any common base (or a custom radix 2–36) and see binary, octal, decimal, and hex instantly. Apply bit widths, signed interpretation, endian byte views, and bitwise ops.

Step-by-step

1. Enter a number and choose or auto-detect radix
2. Optionally set bit width and bitwise operation
3. Copy any of the converted outputs

Worked example

0xFF with 8-bit width shows binary 11111111 and decimal 255, with matching BE/LE byte views.

Use cases

• Translate register dumps between hex and binary
• Inspect little-endian vs big-endian byte order
• Try AND/OR/XOR/shifts while debugging bit flags
