How to Generate a QR Code Online

Generating a QR code online with Gen QR Generator is quick and easy. Follow these simple steps:

  1. 1Navigate to the QR Generator page
  2. 2Enter your website URL in the input field
  3. 3Optionally upload a logo to customize your QR code
  4. 4Select your preferred size, format (PNG, SVG, JPG), and corner style
  5. 5Click 'Generate QR Code' button
  6. 6Preview your QR code and download it in your chosen format

Pro Tip

For best results, ensure your URL starts with https:// and test the QR code before printing or distribution.

Printing QR Codes for Business Cards and Marketing Materials

QR codes are perfect for business cards, flyers, posters, and stickers. Follow these guidelines for print-ready QR codes:

  1. 1Choose a larger size (at least 300x300 pixels) for print quality
  2. 2Select SVG format for scalability without quality loss
  3. 3Alternatively, use PNG format at 600+ pixels for high-resolution prints
  4. 4Ensure high contrast between QR code and background
  5. 5Test the QR code at the intended print size before mass production
  6. 6Leave white space around the QR code (quiet zone) for better scanning

Pro Tip

For business cards, a QR code size of 0.8 x 0.8 inches (2 x 2 cm) works well. For posters and larger materials, scale up proportionally.

Dynamic QR Codes vs Static QR Codes

Understanding the difference between dynamic and static QR codes helps you choose the right option for your needs:

Static QR Codes

  • URL is permanently encoded in the QR code
  • Cannot be changed after generation
  • No tracking or analytics available
  • Perfect for permanent content (WiFi passwords, contact info)
  • Free and works forever
  • No expiration date

Dynamic QR Codes

  • URL can be updated without changing the QR code image
  • Track scans, locations, and devices
  • Perfect for marketing campaigns
  • Redirect users to different content over time
  • Requires premium subscription
  • Analytics dashboard included

Pro Tip

Use static QR codes for permanent information and dynamic QR codes for campaigns that need flexibility and tracking.

Testing and Scanning QR Codes on Mobile Apps

Before distributing your QR codes, always test them to ensure they work correctly across different devices:

  1. 1Use your smartphone's native camera app (iOS 11+ and Android 9+ support QR scanning)
  2. 2Test with popular QR scanner apps like Google Lens or QR Code Reader
  3. 3Check the QR code in different lighting conditions
  4. 4Test at various distances (6 inches to 3 feet works best)
  5. 5Verify the correct URL or content is displayed
  6. 6Test on both iOS and Android devices if possible

Common scanning issues and solutions:

  • QR code too small: Increase the size to at least 2 x 2 cm for print
  • Poor contrast: Use black QR code on white background
  • Damaged or blurry: Regenerate in higher resolution
  • Logo too large: Ensure logo doesn't exceed 15-20% of QR code size
  • Incorrect URL: Double-check the URL before generating

Pro Tip

Most modern smartphones automatically detect QR codes through the camera app. Simply open your camera and point it at the QR code.

Frequently Asked Questions

Are the QR codes I generate free to use?

Yes! All QR codes generated with Gen QR Generator are completely free for personal and commercial use without any limitations or hidden fees.

What file formats are available for download?

You can download your QR codes in PNG, JPG, and SVG formats. SVG is recommended for printing as it's vector-based and scales without quality loss.

Can I edit my QR code after generating it?

Static QR codes cannot be edited once generated. If you need to change the destination URL, you'll need to create a new QR code. For editable QR codes, consider upgrading to our premium dynamic QR code feature.

How do I add a logo to my QR code?

Simply click on Step 2 in the generator and upload your logo image (PNG, JPG, or GIF up to 10MB). The logo will be automatically centered in your QR code with a white background for optimal scanning.

Do QR codes expire?

No, static QR codes generated with Gen QR Generator never expire. They will work indefinitely as long as the destination URL remains active.

What's the minimum size for a scannable QR code?

For print materials, the minimum recommended size is 2 x 2 cm (0.8 x 0.8 inches). For digital displays, 150 x 150 pixels works well. Larger is always better for easier scanning.

Can I track how many times my QR code is scanned?

Static QR codes don't include tracking. For analytics and scan tracking, you'll need to upgrade to our premium dynamic QR code feature which includes a full analytics dashboard.

Why isn't my QR code scanning?

Common issues include: QR code too small, poor image quality, insufficient contrast, damaged print, or incorrect URL format. Ensure your QR code is at least 2x2 cm and test it with multiple devices.
