Number Base Converter
Convert numbers across Binary (base-2), Octal (base-8), Decimal (base-10), and Hexadecimal (base-16) in real time. Features live synchronization and 100% privacy.
How Number Base Converter Works & Technical Principles
Convert numbers across binary, octal, decimal, and hexadecimal bases simultaneously in real time. All calculations run locally in your browser with zero server calls.
Technical Overview: Positional Radix Notation Across Radix Bases
Positional numeral systems represent quantities using a base (radix) b, where each digit position corresponds to an integer power of the radix: sum(d_i * b^i). Converting between bases normalizes values into standard integer representations before formatting into the target positional radix.
Input & Configuration
Type a number into any base field (Binary, Octal, Decimal, or Hexadecimal).
Client-Side Processing
The engine parses the string according to the active radix, validates digit characters, and computes equivalent representations.
Instant Output & Export
All other base fields update simultaneously in real time, ready to copy to your clipboard.
Key Capabilities & Features
Simultaneous 4-Base Synchronization
Editing any single base (base-2, base-8, base-10, or base-16) instantly updates all other bases.
Strict Digit Validation
Prevents invalid characters per base (e.g. rejecting '8' in octal or non-hex characters in base-16).
100% In-Browser Privacy Guarantee
Cryptographic keys, memory addresses, and arithmetic calculations are computed entirely on your device.
One-Click Value Copying
Dedicated copy buttons for each individual base format simplify low-level development workflows.
Standard specification for binary and radix-independent numerical representation
Standard radix prefix notations (0b binary, 0o octal, 0x hexadecimal)
