A QR (Quick Response) code generator creates two-dimensional barcodes that can be scanned by smartphones and QR code readers. QR codes can store various types of data including URLs, text, contact information, Wi-Fi credentials, and more. Our free QR code generator creates high-quality QR codes instantly in your browser, with options to customize size, error correction level, and download in multiple formats.
  1. 1
    Enter Your Data

    Type or paste the content you want to encode into the QR code. This can be a URL, text, email, phone number, or other data.

  2. 2
    Choose QR Code Type

    Select the appropriate type: URL, Text, Email, Phone, SMS, or Wi-Fi. The generator will format the data correctly for each type.

  3. 3
    Customize Appearance

    Adjust the QR code size, error correction level (L, M, Q, H), and choose between light or dark theme. Higher error correction allows the code to work even if partially damaged.

  4. 4
    Generate QR Code

    Click the generate button to create your QR code instantly. The code will appear in the preview area.

  5. 5
    Test the Code

    Use your smartphone camera or a QR code scanner app to test that the code works correctly before downloading.

  6. 6
    Download

    Download your QR code in PNG, SVG, or PDF format. PNG is best for digital use, SVG for scalable graphics, and PDF for printing.

  7. 7
    Use Your QR Code

    Print the QR code or use it digitally. Place it on business cards, flyers, websites, or anywhere you want to share information quickly.

  8. 8
    Share Securely

    Remember that anyone can scan your QR code. Only encode information you are comfortable sharing publicly.

What can I encode in a QR code?

You can encode URLs, plain text, email addresses, phone numbers, SMS messages, Wi-Fi network credentials, contact information (vCard), and more.

How do I scan a QR code?

Most modern smartphones have built-in QR code scanners in their camera apps. Simply open your camera app and point it at the QR code.

What is error correction level?

Error correction allows QR codes to work even if partially damaged or obscured. Levels range from L (lowest, ~7% recovery) to H (highest, ~30% recovery). Higher levels create denser codes but are more reliable.

Are QR codes free to use?

Yes, QR codes are free to generate and use. There are no licensing fees or restrictions for creating or using QR codes.

Can I customize the colors?

Yes, you can customize QR code colors, background, and add logos or images while maintaining scanability. Be careful not to obscure too much of the code.

How much data can a QR code store?

QR codes can store up to 2,953 bytes (about 2.9 KB) of data. The actual capacity depends on the error correction level and data type.

Do QR codes expire?

No, QR codes themselves don't expire. However, if the QR code links to a URL, that URL may become unavailable over time.

Can I track QR code scans?

Our generator creates static QR codes. To track scans, you would need to use a URL shortener service that provides analytics, or host the destination URL on a platform with tracking capabilities.

Are QR codes secure?

QR codes are readable by anyone with a scanner. Never encode sensitive information like passwords or credit card numbers. Always verify the destination before scanning unknown codes.

What file formats are supported?

You can download QR codes as PNG (raster image), SVG (vector image), or PDF (for printing). PNG is best for web use, SVG for scalable graphics, and PDF for professional printing.

Use High Error Correction for Print

Choose Level Q or H error correction when printing QR codes. This ensures the code remains scannable even if it gets scratched, smudged, or partially covered.

Maintain Strong Contrast

Keep dark modules on a light background. Avoid low-contrast color combinations. A minimum 4:1 contrast ratio ensures reliable scanning across devices.

Always Test Before Publishing

Scan your QR code with at least 2-3 different devices and apps before printing or distributing. Check that it decodes correctly and links to the right destination.

Include a Quiet Zone

Leave adequate white space (at least 4 modules wide) around the QR code. This quiet zone helps scanners detect the code boundaries reliably.

Size Appropriately for Distance

As a rule of thumb, the QR code should be at least 1/10th the scanning distance. For a poster viewed from 3 meters away, make the code at least 30cm wide.

Keep Data Short

Shorter data produces simpler, more scannable QR codes. Use URL shorteners for long links. Simpler codes scan faster and print better at smaller sizes.

Add a Call to Action

Always place instructional text near the QR code like "Scan for menu" or "Scan to connect to WiFi." Not everyone recognizes QR codes or knows what action to take.

Link to Mobile-Optimized Pages

When using QR codes for marketing, link to a mobile-optimized landing page. Most QR code scans happen on smartphones. A page that loads poorly on mobile will result in high bounce rates and wasted exposure.

Use SVG Format for Print Materials

Download QR codes as SVG for print materials. SVG is a vector format that scales to any size without losing quality, ensuring your QR code remains sharp and scannable whether it appears on a business card or a billboard.

Use Dynamic QR Codes for Updatable Content

For restaurant menus, event tickets, or product packaging, use dynamic QR codes (via a URL shortener) so you can update the destination without reprinting the code. Static QR codes permanently encode the target URL and cannot be changed after printing.
