The Concept
QR codes are everywhere again. Instead of using random websites with ads, I built a clean generator for personal use.
What I Built
A simple tool that:
- Takes any URL or text
- Generates a QR code instantly
- Download as PNG
- Customizable colors and size
Stack: JavaScript, qrcode.js library
Key Learnings
1. QR generation is simple
The actual encoding is handled by libraries. The value is in clean UI and good UX, not reinventing algorithms.
2. Error correction levels matter
QR codes can survive partial damage. Higher error correction = bigger code but more reliable. Give users the choice.
3. Simple tools have value
Not everything needs to be an app. Sometimes a single HTML page does the job better.
