Create QR codes for any purpose in seconds
Enter data to generate QR code
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.
Select the appropriate type: URL, Text, Email, Phone, SMS, or Wi-Fi. The generator will format the data correctly for each type.
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.
Click the generate button to create your QR code instantly. The code will appear in the preview area.
Use your smartphone camera or a QR code scanner app to test that the code works correctly before downloading.
Download your QR code in PNG, SVG, or PDF format. PNG is best for digital use, SVG for scalable graphics, and PDF for printing.
Print the QR code or use it digitally. Place it on business cards, flyers, websites, or anywhere you want to share information quickly.
Remember that anyone can scan your QR code. Only encode information you are comfortable sharing publicly.
You can encode URLs, plain text, email addresses, phone numbers, SMS messages, Wi-Fi network credentials, contact information (vCard), and more.
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.
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.
Yes, QR codes are free to generate and use. There are no licensing fees or restrictions for creating or using QR codes.
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.
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.
No, QR codes themselves don't expire. However, if the QR code links to a URL, that URL may become unavailable over time.
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.
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.
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.
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.
Keep dark modules on a light background. Avoid low-contrast color combinations. A minimum 4:1 contrast ratio ensures reliable scanning across devices.
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.
Leave adequate white space (at least 4 modules wide) around the QR code. This quiet zone helps scanners detect the code boundaries reliably.
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.
Shorter data produces simpler, more scannable QR codes. Use URL shorteners for long links. Simpler codes scan faster and print better at smaller sizes.
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.
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.
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.
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.
