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.

How do QR Codes work?

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.

Can I change a QR Code after printing?

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.

What is a Dynamic QR Code?

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.

What is a Static 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.

Can I create unlimited QR Codes?

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

How do I create a QR Code?

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.

How do I add a logo to my QR Code?

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.

How do I scan a QR Code?

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.

Can I create QR Codes offline?

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

What size should a QR Code be?

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.

Can I print QR Codes?

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.

Can QR Codes track scans?

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.

Can I create QR Codes for WiFi?

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.

Can I create QR Codes for PDF?

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.

What is the best QR Code Generator?

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.

Scan Tracking	Not possible	Track scans, location, device, time
Size	Larger with more data	Smaller — fixed short URL length
Best For	Permanent links, WiFi passwords, vCards	Marketing campaigns, frequently changing URLs
Expiration	Never expires	Can have expiry dates
Cost	Always free	May require paid service for analytics

QR Code Error Correction Levels

QR codes have built-in error correction that allows them to be read even if partially damaged or obscured. Higher levels add more redundancy.

Level L (Low) — 7% recovery

Best for clean environments where the QR code won't be damaged. Produces the smallest QR codes. Use for digital screens and clean print.

Level M (Medium) — 15% recovery

Good balance of size and durability. Suitable for most print materials like flyers, posters, and business cards.

Level Q (Quartile) — 25% recovery

Recommended when adding a logo to the center of your QR code. The logo covers part of the code, so higher error correction compensates.

Level H (High) — 30% recovery

Maximum durability. Use for outdoor signage, product packaging, or anywhere the QR code might be exposed to wear and tear. Best choice when adding a logo.

QR Code Best Practices

Follow these guidelines to ensure your QR codes scan reliably every time.

Maintain a Quiet Zone

Always keep a blank margin (quiet zone) around the QR code — at least 4 modules wide. This helps scanners detect the code boundaries.

Minimum Size for Print

For printed materials, the QR code should be at least 2 x 2 cm (0.8 x 0.8 inches). For posters and signage viewed from a distance, scale up proportionally.

Use High Error Correction with Logos

When placing a logo in the center, set error correction to Level Q or H (25–30%). This ensures the code still scans despite the logo covering part of it.

Ensure Color Contrast

The foreground (dark) modules must contrast strongly with the background (light). Dark on light works best. Never put dark QR codes on dark backgrounds.

Test Before Printing

Always scan your QR code with multiple devices (iPhone, Android, different apps) before printing a large batch.

Use PNG or SVG for Print

Download as SVG for scalable vector quality, or PNG at 500px+ for raster prints. Avoid JPG for print due to compression artifacts.

Keep URL Short

Shorter URLs produce simpler, smaller QR codes that scan faster and are more reliable. Use the built-in URL shortener for long links.

QR Code Design Tips

Make your QR codes visually appealing while keeping them scannable.

Add Your Brand Logo

Place your company logo or an emoji in the center of the QR code. Use error correction Level H to maintain scannability. Keep the logo under 30% of the QR code area.

Use Custom Colors

Match your brand colors — but always keep high contrast. Use dark foreground on light background. Test after changing colors.

Choose a Dot Shape

Square dots look technical, rounded dots feel modern, and circle dots give a friendly appearance. Match the style to your brand.

Add a Call-to-Action

Place text like 'Scan Me' or 'View Menu' above or below the QR code to increase scan rates.

Use Frames

A border frame around the QR code draws attention and provides space for your call-to-action text.
