Free QR Code Generator Tool Built From Scratch (Source Included)

🧾 Build Your Own Customizable QR Code Generator (No Libraries Needed!)

These days, QR codes are used everywhere — for payments, links, login, and more.
I wanted to build a simple tool that could generate QR codes quickly without relying on any external libraries or showing ads.

So I built this project using just HTML, CSS, and JavaScript — and it’s fully customizable.

How It’s Built

This project uses:

HTML for the structure

CSS for the styling and layout

JavaScript to generate the QR code using qrcode.js
No frameworks or heavy libraries — it’s all built from scratch.

Why I Made This:
I was exploring ideas for small frontend projects, and QR codes seemed like a fun and useful thing to build.
I also wanted full control over the look and features, which is hard to get with online tools.
