Integer Base Converter

What is an Integer Base Converter?

The Integer Base Converter allows you to convert whole numbers between different number systems—such as binary, octal, decimal, hexadecimal, and custom bases—instantly with arbitrary precision support.

Why Use This Converter?

  • Low-Level Programming: Inspect binary bitmasks, hexadecimal memory addresses, and octal file permissions.
  • Computer Science Learning: Verify manual homework conversions between base-2, base-8, base-10, and base-16.
  • Web Development: Convert hex color codes or byte representations into decimal numbers.

How to Use

  1. Enter your source number into the input field.
  2. Choose the input base (e.g., Decimal base 10 or Hex base 16).
  3. Read the converted outputs across all standard bases simultaneously.

Real Conversion Example

Input (TEXT):

Decimal: 255

Output (TEXT):

Binary (Base 2): 11111111
Octal (Base 8): 377
Hexadecimal (Base 16): FF

Important Technical Details & Mechanics

  • BigInt Support: Uses JavaScript BigInt under the hood to prevent overflow errors on large 64-bit integers.
  • Case Insensitive Input: Accepts both lowercase and uppercase hex characters (a-f / A-F).
  • Zero Dependency: Runs 100% locally in your browser with zero server latency.

Frequently Asked Questions

What bases does this tool support?

It supports standard Binary (2), Octal (8), Decimal (10), Hexadecimal (16), and custom bases up to Base 64.

Can it convert very large numbers without losing accuracy?

Yes. It uses native BigInt calculations to handle arbitrarily large integers cleanly.

Is my input sent to a backend server?

No, all calculations execute client-side in your browser.

Does it support negative numbers?

Yes, negative sign representations are preserved across base conversions.

What is the main function of Integer Base Converter?

Convert numbers between Binary (Base 2), Octal (Base 8), Decimal (Base 10), Hexadecimal (Base 16), and custom bases up to Base 64. This converter transforms integer base data formats locally without server uploads.
