Enter your text and click "Generate QR Code" to create a scannable QR code!
Type or paste the text, URL, email, phone number, or any data you want to encode into a QR code. Our generator supports all standard QR code content types.
Select the appropriate size (100-500px), error correction level, and output format. Higher error correction allows scanning even when the code is partially damaged.
Click "Generate QR Code" to create your code instantly. Download it in your preferred format (PNG, JPG, GIF, or SVG) for immediate use.
Always test your QR code with multiple devices and scanning apps to ensure it works correctly before using it in production or printing.
Use our preset templates for common QR code types like URLs, emails, phone numbers, SMS, WiFi credentials, and vCards. These ensure proper formatting and compatibility.
Choose from Low (7%), Medium (15%), Quartile (25%), or High (30%) error correction. Higher levels create larger codes but work even when damaged or partially obscured.
Export as PNG for general use, JPG for smaller files, GIF for web compatibility, or SVG for scalable vector graphics that maintain quality at any size.
Direct users to websites, landing pages, or specific web content without typing long URLs.
Enable instant email composition with pre-filled recipient, subject, and message content.
Allow instant phone calls without manual dialing. Perfect for contact sharing and emergency information.
Pre-compose text messages with recipient and content. Useful for feedback requests and promotions.
Share WiFi network access instantly without revealing passwords. Great for guest access and events.
Share complete contact information including name, phone, email, and address in one scan.

QR (Quick Response) codes are two-dimensional matrix barcodes that can store various types of data. They consist of black squares arranged on a white background, with three position markers in the corners for orientation detection.
QR codes use Reed-Solomon error correction, allowing them to remain readable even when up to 30% of the code is damaged or obscured. This makes them ideal for outdoor use and situations where wear and tear is expected.
Our QR code generator processes your data securely. While we use a trusted external API for generation, your sensitive data is handled with care and not stored on our servers.
QR codes themselves don't track users, but the destinations they link to might. Always inform users about data collection and use privacy-respecting analytics when tracking QR code usage.
A: Error correction determines how much of the QR code can be damaged while still remaining scannable. Low (7%) is good for clean environments, Medium (15%) for general use, Quartile (25%) for outdoor use, and High (30%) for harsh conditions where damage is likely.
A: Static QR codes (like those generated by this tool) cannot be edited once created. To change the content, you need to generate a new QR code. Dynamic QR codes (available through specialized services) allow content updates but require ongoing service subscriptions.
A: For print, QR codes should be at least 2cm x 2cm (about 0.8 inches). The scanning distance follows a 10:1 ratio - for every 10 units of distance, the QR code should be 1 unit in size. For business cards, 1.5-2cm works well; for posters, 5-10cm is recommended.
A: Common issues include: too small size, poor contrast, damaged or dirty surface, wrong format encoding, or incompatible scanner app. Ensure good lighting, clean surface, and try different scanning apps. Test your QR code immediately after creation.
A: QR codes themselves are not encrypted, so avoid including passwords, personal IDs, or sensitive data directly. Instead, link to secure websites (HTTPS) where users can safely enter sensitive information. For high-security applications, consider encrypted QR code solutions.
A: Static QR codes (like ours) never expire - they permanently encode the data you specify. However, if they link to a website or service, that destination might become unavailable. Dynamic QR codes from paid services may expire if subscriptions lapse.
A: While our basic generator creates standard black-and-white codes, you can customize colors, add logos, and modify designs using specialized tools. However, be cautious - too much customization can reduce scannability. Always test extensively after customization.
A: PNG is best for general use and print (lossless, transparent background support). JPG for smaller file sizes when transparency isn't needed. SVG for scalable graphics that maintain quality at any size (ideal for logos and large prints). GIF for basic web use and animations.
