QR Code Generator

A QR (Quick Response) Code is a two-dimensional barcode that stores data — URLs, text, contact info, WiFi credentials, and more. It can be scanned instantly by any smartphone camera, making it a bridge between physical and digital worlds.

A QR code encodes data into a grid of black and white squares. When your smartphone camera scans it, a QR reader app decodes the pattern and performs the associated action — opening a URL, connecting to WiFi, adding a contact, etc.

Yes, our QR code generator is completely free. You can create unlimited QR codes with no signup, no watermarks, and no expiration. All processing happens in your browser.

Static QR codes (those with encoded data) never expire. Dynamic QR codes that point to a short URL may expire depending on the service. Our generator creates static QR codes that last forever.

Static QR codes cannot be changed once printed — the data is permanent. Dynamic QR codes can be updated to point to a new destination without reprinting. If you need flexibility, use a dynamic approach.

A dynamic QR code contains a short URL that redirects to your destination. This lets you change the destination, track scans, and add analytics — all without reprinting the QR code.

A static QR code encodes the actual data (URL, text, WiFi info) directly in the QR pattern. It works without any server, never expires, and is completely free — but cannot be edited after creation.

Yes. There are no limits on how many QR codes you can generate. Create as many as you need for free.

Enter your content (URL, text, WiFi details, contact info), customize the appearance (colors, logo, size), and download. The entire process takes seconds and happens in your browser.

Use the logo upload option in the customization panel. Select an image file or choose an emoji. For best results, use error correction Level Q or H (25–30%) so the QR code still scans with the logo covering part of it.

Open your smartphone camera (iPhone and most Android phones have built-in QR scanning). Point it at the QR code. A notification or link will appear — tap to open. You can also use any QR scanner app.

Yes. Our QR code generator runs entirely in your browser. Once the page loads, you can generate QR codes without an internet connection.

For print: minimum 2 x 2 cm (0.8 inches). For business cards: 2.5 x 2.5 cm. For posters: scale up based on viewing distance. For screens: at least 200 x 200 pixels. Always maintain the quiet zone (blank margin) around the code.

Yes. SVG is ideal for print materials because it scales to any size without losing quality. Download as SVG for business cards, posters, or any vector-based design.

Yes. Choose between PNG with transparent background (for overlaying on designs) or PNG with white background (for direct use). Sizes from 200px to 1000px are available.

Absolutely. Download as SVG for professional print or PNG at 500px+ for standard printing. Test the printed QR code with multiple devices before a large print run.

Static QR codes cannot track scans. Dynamic QR codes (which use a redirect URL) can track scan count, location, device type, and time. For analytics, you would need a dynamic QR code service.

Yes. Enter your WiFi network name (SSID), password, and encryption type. The generated QR code lets guests connect to your WiFi by simply scanning — no typing the password.

Yes. Encode a PDF document URL into a QR code. When scanned, it opens the PDF directly on the user's phone — perfect for menus, brochures, manuals, and reports.

The best QR code generator is one that is free, private, supports multiple QR types, offers customization (colors, logo, shapes), downloads in multiple formats (PNG, SVG), and runs client-side for privacy. Our tool offers all of these features.
