What Is a QR Code Generator?
A QR code generator is a tool that converts text, URLs, contact information, or other data into a scannable two-dimensional barcode. QR codes (Quick Response codes) can store significantly more information than traditional barcodes and can be scanned using smartphone cameras, making them ideal for bridging physical and digital experiences.
Our QR code generator offers professional-grade customization options including color selection, size adjustment, error correction levels, and multiple export formats. Whether you need a QR code for marketing materials, business cards, product packaging, or event tickets, our tool provides everything you need to create high-quality, scannable codes.
The tool works entirely in your browser, ensuring your data remains private and secure. Generate unlimited QR codes for free without registration, watermarks, or usage restrictions. All codes are static, meaning they never expire and will work forever as long as the physical code remains readable.

Size: 400px
Error Correction: High (for table tents)
Use Case:
Place QR codes on table tents or menus to let customers view your digital menu, reducing physical contact and making updates easier.
Example 2: Business Card Contact
Type: Email
Email: [email protected]
Subject: Let's connect
Colors: Brand colors (navy blue on white)
Use Case:
Add a QR code to business cards that opens a pre-filled email, making it easy for contacts to reach out without typing your email address.
Example 3: Event Registration
Type: URL
Content: https://events.com/register/conference2024
Size: 600px (for posters)
Format: SVG (for printing)
Use Case:
Print QR codes on event posters and flyers to drive registrations. Attendees can scan to instantly access the registration page.
Understanding QR Code Technology
QR codes use a matrix of black and white squares to encode information in a two-dimensional format. Unlike traditional barcodes that store data in one dimension, QR codes can hold significantly more information - up to 4,296 alphanumeric characters or 7,089 numeric characters.
Key Components of a QR Code:
Position Markers: Three large squares in corners help scanners detect and orient the code
Alignment Patterns: Smaller squares that help with scanning accuracy, especially for larger codes
Timing Patterns: Alternating modules that help determine the code's size and structure
Data Area: The main section containing your encoded information
Error Correction: Redundant data that allows the code to be read even if partially damaged
Error correction is particularly important for QR codes. Using Reed-Solomon error correction, QR codes can recover data even when up to 30% of the code is damaged or obscured. This makes them reliable for outdoor use, printed materials, and situations where the code might get dirty or partially covered.
Tips & Best Practices
Ensure Sufficient Contrast
Always use dark colors on light backgrounds for maximum scannability. While our tool allows custom colors, black on white provides the most reliable scanning across all devices and lighting conditions.
Choose the Right Size
For print materials, ensure your QR code is at least 2cm x 2cm (0.8 inches). Larger codes (5-10cm) work better for scanning from a distance, such as on billboards or posters. For digital use, 300-500 pixels is typically sufficient.
Test Before Printing
Always test your QR code with multiple devices and scanning apps before mass printing. Scan it in different lighting conditions and from various distances to ensure reliability.
Use High Error Correction for Logos
If you plan to add a logo or image to the center of your QR code, use High (30%) error correction. This ensures the code remains scannable even with the logo covering part of the data area.
Keep URLs Short
Shorter URLs create simpler QR codes with fewer modules, making them easier to scan. Consider using URL shorteners for long web addresses, but ensure the shortened URL is from a reliable service.
Add a Call-to-Action
Include text near your QR code explaining what users will get when they scan it. For example, "Scan to view menu" or "Scan for special offer" increases scan rates significantly.
Common Mistakes to Avoid
Using Low Contrast Colors
Avoid using similar colors for foreground and background (like light gray on white or dark blue on black). Insufficient contrast makes QR codes difficult or impossible to scan. Stick to high-contrast combinations for reliability.
Making QR Codes Too Small
Tiny QR codes are frustrating to scan. If your code is smaller than 2cm x 2cm in print, users will struggle to scan it. Always consider the scanning distance - codes meant to be scanned from far away need to be proportionally larger.
Distorting or Stretching
QR codes must maintain their square aspect ratio. Stretching or distorting the code will make it unscannable. If you need to resize, always maintain the original proportions. Use SVG format for scaling without quality loss.
Placing on Curved or Textured Surfaces
While QR codes can handle some distortion, placing them on highly curved surfaces (like bottles) or heavily textured materials can reduce scannability. If you must use curved surfaces, increase the error correction level.
Forgetting to Test
Never assume your QR code works without testing. Different phones and scanning apps may behave differently. Test with multiple devices, especially older smartphones, to ensure broad compatibility.
Using Broken or Expired Links
Since static QR codes can't be updated, ensure your URLs are permanent and won't change. If you're using a URL shortener, choose a reliable service that won't expire your links. Test the destination URL before printing.
Frequently Asked Questions
What is a QR code?
A QR code (Quick Response code) is a two-dimensional barcode that can store various types of information like URLs, text, contact details, or phone numbers. It can be scanned using a smartphone camera to quickly access the encoded information.
Are the QR codes generated free to use?
Yes, all QR codes generated with our tool are completely free to use for personal and commercial purposes. There are no hidden fees, watermarks, or usage restrictions. You own the QR codes you create.
What error correction level should I choose?
Error correction allows QR codes to be readable even if partially damaged. Low (7%) is suitable for clean environments, Medium (15%) for general use, Quartile (25%) for outdoor use, and High (30%) for harsh conditions or when adding logos.
Can I customize the colors of my QR code?
Yes, you can customize both the foreground (dark) and background (light) colors of your QR code. However, ensure sufficient contrast between colors for reliable scanning. Dark foreground on light background works best.
What file formats can I download?
You can download your QR code in three formats: PNG (raster image, best for digital use), SVG (vector format, scalable without quality loss), and PDF (ideal for printing and professional documents).
Do QR codes expire?
Static QR codes (like those generated by our tool) never expire. The information is encoded directly in the QR code itself, so it will work forever as long as the physical code remains readable.
How do I add a logo to my QR code?
While our current version focuses on core functionality, you can add a logo using image editing software after downloading. Choose a high error correction level (Quartile or High) to ensure the QR code remains scannable with the logo overlay.
What size should I make my QR code?
For digital use, 300-500 pixels is sufficient. For printing, use at least 2cm x 2cm (about 0.8 inches) for close-range scanning. Larger sizes (5-10cm) are better for scanning from a distance. Our tool lets you adjust size from 100 to 1000 pixels.
