Convert numbers between Binary, Decimal, Hexadecimal, and any custom base up to 36. It’s super fast, works in real-time, and handles all those weird bases your teacher might throw at you.

Number systems are literally the language of computers, but let’s be real, converting them by hand is a pain. While we usually stick to Base 10 (Decimal) in class, computers love Binary (Base 2) for their logic gates, and Hexadecimal (Base 16) is a lifesaver for reading memory addresses or picking web colors. Our Number Base Converter is here to save you from tedious long division. Whether you’re a CS student trying to figure out bytes and nibbles for a project, or just curious about how numbers work under the hood, this tool makes it easy. We handle all the standard stuff plus custom bases up to 36, so you can focus on building cool stuff instead of stressing over math errors. I remember the first time I had to convert a 32-bit binary string to Hex in my elective CS course—it took me ten minutes and I still got one digit wrong. With this tool, that doesn’t happen. You type, it converts, and everything stays in sync. It’s also great for understanding how data is actually stored in memory. For instance, did you know that one Hex digit perfectly represents four bits? That’s why developers use it so much—it’s like a "compact" version of binary. Our tool even supports "BigInt," so you can convert massive numbers that would crash a normal calculator. And as always, the best part is the privacy. Most other "converter" sites send your numbers back to a server to be processed. If you’re working on a security project or a private key, you *really* shouldn’t be sharing that. On Filemint, the math happens entirely on your machine using native JavaScript BigInt logic. It’s fast, it’s secure, and it’s always one hundred percent private.

Privacy Architecture

This tool uses client-side WebAssembly to ensure your data never touches a server. Secure, fast, and 100% private by design.

Core Capabilities

  • Real-time conversion across Binary, Octal, Decimal, and Hex
  • Custom base slider supporting Bases 2 to 36
  • BigInt support for ultra-large number conversion
  • Interactive Bit-Flipper (64-bit visualizer)
  • Bitwise logic tester (AND, OR, XOR, NOT)
  • Error highlighting for invalid characters in specific bases
  • 100% private and runs entirely in your browser

Why It Matters

  • Accuracy: Eliminate mental math errors in your homework or projects.
  • Learning: Visualize how numbers change as they move between systems.
  • Speed: No "calculate" button—get results as fast as you can type.
  • Privacy: Your sensitive numerical data never leaves your computer.

Quick Start Guide

01

Just punch your number into any of the fields—Binary, Hex, or Decimal. The tool detects what you’re doing instantly.

02

The tool updates all the other bases in real-time. No "Submit" button needed—it’s faster than your keyboard.

03

Use the custom base slider if you need to convert to something weird like Base 13 or Base 36. We use A-Z for digits above 9.

04

Switch to the Interactive Bits tab if you want to see exactly which 0s and 1s make up your number. You can even click the switches to flip them!

05

Use the bitwise tab to play logic games with your numbers like AND, OR, and XOR to see how computer logic actually works.

Technical Architecture

BigInt & Radix Logic

We use the native `BigInt` type in JavaScript to handle arbitrary-precision integers. The conversion is performed using `BigInt.prototype.toString(radix)` for output and `BigInt("0x" + input)` style casting for input parsing, ensuring zero precision loss.

Interactive 2D Bit-Grid

The bit-flipper uses a reactive state array of 64 booleans. When you click a bit, we recalculate the entire integer value using bitwise shifts (`1n << BigInt(index)`), providing a high-performance visual representation of binary data.

Tokenized Input Validation

We use a dynamic regex engine to validate inputs in real-time. For example, if you are in Binary mode and type a "2", the tool highlights the field in red instantly by checking the input against the character set allowed by the current radix.
