Quick Examples
How the QR Code Generator Works
This tool uses the qrserver.com API to generate QR codes instantly. Type or paste your content - a URL, text, email address, or phone number - and the API encodes it into a 2D barcode pattern.
QR codes use Reed-Solomon error correction, which means they can still be scanned even if partially damaged or obscured. You can choose different error correction levels depending on how much of the code might get blocked (like by a logo in the center).
The generator supports multiple output formats: PNG for general use, SVG for scalable vector graphics (perfect for print), and JPG for compatibility. Adjust the size from 100px to 600px depending on where you'll use the code.
Customization options let you change the foreground color (the actual QR pattern) and background color. Just remember: high contrast is essential for scanability. Dark QR on light background works best.
The preview updates automatically as you type, so you can see exactly how your QR code will look before downloading. No need to click generate repeatedly.
When You'd Actually Use This
Creating restaurant menu QR codes
Put a QR code on tables that links to your digital menu. Customers scan with their phone and instantly see your offerings. Update the menu URL seasonally without reprinting - the QR code stays the same.
Sharing Wi-Fi passwords with guests
Create a QR code with your Wi-Fi network name and password. Guests scan it and their phone automatically connects. No more spelling out "it's capital T, underscore, then the number 7..."
Adding product information to packaging
Small products can't fit detailed instructions. Add a QR code linking to setup videos, ingredient lists, or troubleshooting guides. Customers get full information without cluttering your design.
Creating contact cards for networking
Encode your vCard contact info in a QR code. Put it on business cards or show it on your phone at events. People scan and instantly have your name, email, phone, and LinkedIn profile.
Setting up event check-in systems
Generate unique QR codes for each attendee's ticket. At the event, scan codes to mark people as arrived. Works for conferences, weddings, or any ticketed gathering.
Linking physical displays to digital content
Museum exhibits, retail displays, or real estate signs can include QR codes. Visitors scan to see videos, additional photos, or detailed specifications without needing to type URLs.
What to Know Before Using
Test before printing.Always scan your QR code with multiple phones (iOS and Android) before mass printing. What looks scannable on screen might not work at small sizes or with certain camera apps.
Size matters for scanning distance.A 100px QR code works on business cards viewed from 6 inches. A 600px code is needed for posters scanned from several feet away. Rule of thumb: 1 inch of QR code per 10 feet of scanning distance.
Color contrast is critical.Light QR patterns on dark backgrounds often fail to scan. The camera needs to distinguish the pattern from the background. Black on white is most reliable.
URL length affects complexity.Longer URLs create denser QR codes with more tiny squares. Use a URL shortener for long links - shorter URLs produce simpler, more scannable codes.
Pro tip: For printed materials, always download SVG format. Vector graphics scale to any size without pixelation. PNG is fine for digital use, but SVG ensures crisp prints at any size.
Common Questions
Can I create a QR code for my Wi-Fi network?
Yes! Use the format: WIFI:T:WPA;S:YourNetworkName;P:YourPassword;; The T is security type (WPA, WEP, or nopass), S is network name, P is password. Phones will automatically prompt to join when scanned.
What's the difference between PNG, SVG, and JPG?
PNG has transparent background and sharp edges - best for digital use. SVG is vector (infinitely scalable) - best for print. JPG is universally compatible but loses quality at large sizes.
How small can I print a QR code?
Minimum recommended size is 0.8 x 0.8 inches (2 x 2 cm) for close-up scanning. Business card QR codes work at this size. For scanning from distance, go much larger - 3+ inches for posters.
Can I add my logo to the QR code?
This basic generator doesn't support logo embedding. For logo QR codes, use a tool that supports error correction level H (30% redundancy) so the logo doesn't break scannability.
Do QR codes expire?
The QR code itself never expires - it's just a visual representation of data. But if it links to a URL and that page goes down, the QR code becomes useless. The code doesn't expire; the content might.
Why won't my QR code scan?
Common issues: low contrast colors, too small when printed, damaged/cut off edges, or the encoded URL is malformed. Test with multiple phone cameras and ensure high contrast between foreground and background.
Can I track how many people scan my QR code?
Not directly - QR codes are just data. But if you link to a URL you control, use UTM parameters or a link shortener with analytics. Then track clicks, which approximate scans.
