About QR 코드 생성기

OptiPix QR Code Generator lets you create and scan QR codes entirely in your browser. Generate QR codes from URLs, plain text, email addresses, phone numbers, WiFi credentials, or any text content. Customize the output with adjustable size, error correction level, and foreground/background colors. The generator produces crisp, high-resolution QR codes that you can download as PNG images. The built-in scanner uses your device's camera or lets you upload an image containing a QR code to decode its content. Both generation and scanning happen locally with no server interaction. QR codes are widely used for contactless menus, event tickets, business cards, WiFi sharing, payment links, and marketing campaigns. The tool supports all standard QR code error correction levels (L, M, Q, H) so codes remain scannable even if partially damaged or obscured.

How It Works

The generator uses the qrcode library to encode your text into a QR code matrix following the ISO/IEC 18004 standard. The scanner uses the jsQR library to detect and decode QR codes from images using pattern recognition algorithms.

Use Cases

•Create QR codes for business cards and marketing materials
•Generate WiFi sharing QR codes for guests
•Create QR codes for event tickets and check-ins
•Generate payment link QR codes
•Scan and decode QR codes from images

Frequently Asked Questions

What can I encode in a QR code?

You can encode URLs, plain text, email addresses, phone numbers, WiFi credentials, and any other text content. The QR code standard supports up to about 4,000 alphanumeric characters.

Can I customize the QR code appearance?

Yes. You can adjust the size, error correction level, and foreground/background colors. Higher error correction allows more customization while keeping the code scannable.

What is error correction?

Error correction allows QR codes to be read even when partially damaged. Level L recovers 7% damage, M recovers 15%, Q recovers 25%, and H recovers 30%. Higher levels produce larger codes.
