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 Wi-Fi credentials. When scanned with a smartphone camera or QR code reader app, it instantly decodes and displays or acts on the information. QR codes were invented in 1994 and have become widely used for marketing, payments, contactless interactions, and information sharing.

How do I create a QR code for a website?

Select "URL / Website" as the content type, enter the full website address (including https://), customize the size and colors if desired, then click "Generate QR Code". The resulting QR code will open the website when scanned. You can also use plain text for URLs, but using the URL type ensures the proper format.

What are error correction levels and which should I use?

Error correction levels determine how much redundant data is included to recover from damage: Low (7%), Medium (15%), Quartile (25%), and High (30%). Use Low or Medium for digital use where the QR code won't be damaged. Use Quartile or High for print materials, outdoor displays, or environments where the code might get partially obscured, dirty, or damaged. Higher error correction creates slightly larger QR codes.

Can I customize the colors of my QR code?

Yes! You can customize both the QR code color (the dark squares) and background color. While you can choose any colors, it's important to maintain good contrast for reliable scanning. Dark QR codes on light backgrounds work best. Avoid low contrast combinations like light gray on white, or similar colors that blend together. Most smartphones can scan colored QR codes, but black and white is the most universally compatible.

How do I create a Wi-Fi QR code?

Select "Wi-Fi Network" as the content type, enter the network name (SSID), choose the security type (WPA/WPA2, WEP, or no password), and enter the password if required. Optionally check "Hidden network" if the SSID is not broadcast. When someone scans this QR code, their device will automatically connect to the Wi-Fi network without manually entering the password.

What is a vCard QR code?

A vCard QR code contains contact information that, when scanned, automatically adds the contact to the recipient's phone address book. It can include full name, phone number, email, company, job title, website, and address. This is perfect for business cards, networking events, or sharing contact details digitally. The recipient just scans the code and taps "Add Contact" to save your information.

What size QR code should I use?

For digital use (screens, websites, emails), 256px to 512px is sufficient. For print materials like business cards or flyers, use 512px or larger. For large prints like posters or banners, use 1024px or higher. The QR code should be at least 2cm (0.8 inches) in physical size when printed for reliable scanning. You can always scale down a larger QR code, but scaling up can cause pixelation.

Are QR codes generated by this tool safe to use?

Yes, absolutely. All QR code generation happens entirely in your browser using client-side JavaScript. Your information is never sent to our servers or stored anywhere. This means your Wi-Fi passwords, contact details, and any other sensitive data remain completely private on your device. The QR code is generated locally and downloaded directly to your computer or phone.

Can I use QR codes commercially?

Yes, QR codes generated by this tool are completely free to use for any purpose including commercial use. There are no watermarks, attribution requirements, or licensing restrictions. You can use them for business cards, marketing materials, product packaging, websites, or any other commercial application. The Denso Wave patent for QR codes has expired, making the QR code format itself free to use.

Why is my QR code not scanning?

If your QR code isn't scanning, check: 1) Sufficient contrast between QR code and background colors, 2) The code isn't distorted or stretched (keep it square), 3) It's printed at an adequate size (at least 2cm physical), 4) The code isn't damaged or partially covered, 5) Good lighting when scanning, 6) Your scanner app supports the content type. If using colors other than black/white, ensure high contrast. Try generating with default settings first to confirm the code works.

About QR Code Generator

QR Code Generator is a powerful tool that creates two-dimensional barcodes (QR codes) for encoding various types of information. QR codes were invented in 1994 by Denso Wave (a Toyota subsidiary) for tracking automotive parts, but have since become ubiquitous in marketing, payments, and information sharing. QR codes use a pattern of black and white squares arranged on a grid to encode data that can be quickly scanned by smartphones and other devices. When scanned, the code is decoded and the device takes action—opening a URL, adding a contact, connecting to Wi-Fi, or displaying text. Our QR Code Generator supports multiple content types: URLs for websites, plain text for notes, email addresses for mailto: links, phone numbers for tel: links, SMS messages for text messaging, Wi-Fi credentials for automatic network connection, and vCard contacts for address books. You can customize the QR code size from 128px to 2048px, making it suitable for both digital use and print materials. Choose custom colors for both the QR code and background to match your brand identity, though high contrast ensures better scannability. Select from four error correction levels—Low (7%), Medium (15%), Quartile (25%), and High (30%)—to balance code size with damage tolerance. Higher error correction is recommended for print materials where the QR code might get partially damaged, dirty, or obscured. All QR code generation happens entirely in your browser using JavaScript—your content, credentials, and data are never sent to our servers. This makes it safe to generate QR codes for sensitive information like private Wi-Fi passwords, personal contact details, or internal URLs. Download your QR codes as PNG images with 2x resolution for crisp printing, or use them directly in digital materials. Perfect for business cards with contact QR codes, marketing materials directing customers to websites, restaurant menus and ordering systems, event tickets and registration links, Wi-Fi sharing for guests without verbal passwords, product packaging links to manuals and support, payment links or cryptocurrency addresses, educational scavenger hunts and interactive experiences. Use this tool to create custom QR codes that connect the physical world with digital information in a single scan.

Unlike many online tools that require account creation or have hidden costs, QR Code Generator is completely free and requires no signup. Simply open the tool and start using it immediately. Your privacy is our priority - all processing happens locally in your browser, and your data is never stored on our servers.
