What Is a QR Code Generator?
A QR Code Generator transforms any text or URL into a scannable QR (Quick Response) code — a two‑dimensional barcode that can be read by smartphones and dedicated QR scanners. QR codes are used everywhere: from sharing links and contact information to enabling payments and accessing Wi‑Fi networks. This tool gives you full control over the QR code's appearance and error correction level. It uses the qrcode.js library[reference:4], a lightweight, dependency‑free JavaScript library that renders QR codes as HTML5 Canvas elements.[reference:5] All processing happens locally in your browser — nothing is ever uploaded to a server.
How to Use
- Enter your text or URL in the content area — anything you want to encode in the QR code.
- Customize the QR code — adjust the size, choose an error correction level, and pick foreground/background colors.
- Click "Generate QR" — the QR code appears instantly in the preview panel.
- Download the QR code as a PNG image with the Download button, or clear everything with the Clear button.
Frequently Asked Questions
What is error correction and which level should I choose?
Error correction allows QR codes to be read even if they're partially damaged or obscured. Low (L) recovers ~7% of data, Medium (M) ~15%, Quartile (Q) ~25%, and High (H) ~30%. Higher levels create larger QR codes but are more resilient. Medium is a good balance for most use cases.
Does this tool work offline?
Yes. Once the page loads, all processing happens locally in your browser using the qrcode.js library.[reference:6] No network requests are made for generating QR codes.
What data can I encode in a QR code?
You can encode any text — URLs, contact information, Wi‑Fi credentials, plain text, and more. QR codes support up to 4,296 alphanumeric characters or 7,089 numeric characters, depending on the version and error correction level.
Disclaimer: This tool performs all operations locally in your browser. No data is stored, transmitted, or logged. You are responsible for ensuring you have the rights to use any content you encode in QR codes.
