QR Kit — Instant QR Code Generator

A QR code (Quick Response code) is a two-dimensional barcode that can store various types of information such as URLs, Wi-Fi credentials, or contact information. It can be scanned by smartphones and other devices with a camera. QR codes were invented in 1994 by Denso Wave, a subsidiary of Toyota, for tracking automotive parts during manufacturing. Today, they're used worldwide for everything from marketing campaigns to contactless payments. The 'Quick Response' name refers to the code's ability to be decoded at high speed compared to traditional barcodes.

Select the Wi-Fi tab, enter your network name (SSID), choose the security type (WPA/WPA2, WEP, or None), enter the password if required, and optionally mark if it's a hidden network. The QR code will be generated automatically as you type. This QR code can be scanned by any modern smartphone (iOS 11+ or Android 10+) to automatically connect to your network without manually entering the password. It's perfect for guest networks, coffee shops, hotels, or anywhere you want to share Wi-Fi access conveniently and securely. The credentials are encoded in a standardized WIFI: format that all major smartphone operating systems recognize.

A vCard QR code contains contact information such as name, phone number, email, company, and address in a digital business card format. When scanned, it can automatically add the contact to the user's phone contacts app without manual data entry. vCard (Virtual Contact File) is an industry-standard format supported by virtually all smartphones and contact management applications. This makes vCard QR codes ideal for business cards, email signatures, conference badges, and networking events. Instead of manually typing contact details or exchanging physical business cards that can be lost, people can simply scan your vCard QR code to instantly save your information.

No, absolutely not. All QR code generation happens entirely in your web browser using client-side JavaScript. We don't store, upload, or track any of your data. Your Wi-Fi passwords, URLs, contact information, and any other data you enter never leaves your device. This client-side approach ensures complete privacy and security—your sensitive information stays under your control at all times. You can even use QR Kit offline once the page has loaded. We built QR Kit with a privacy-first philosophy because we believe your data belongs to you and only you. Unlike many online QR code generators that require registration or upload your data to their servers, QR Kit processes everything locally in your browser.

Use the color pickers in the customization section to change the foreground (the dark pattern squares) and background (the light area behind the pattern) colors of your QR code. You can also enter hex color codes directly for precise color matching. When customizing colors, ensure sufficient contrast between foreground and background (at least 50% difference) so the QR code remains scannable by cameras. Dark foreground on light background works best. Avoid low-contrast combinations like light gray on white or dark blue on black, as these can make scanning difficult or impossible. You can match your brand colors while maintaining scannability by testing the QR code with multiple devices after customization.

You can download your QR code as SVG (Scalable Vector Graphics) or PNG (Portable Network Graphics). SVG is a vector format that scales infinitely without quality loss, making it perfect for print materials like posters, business cards, banners, and signage where you need crisp edges at any size. PNG is a raster format with a fixed resolution, ideal for digital use such as websites, social media posts, email signatures, and mobile apps. For professional printing, always choose SVG. For quick digital sharing or when file size matters, PNG works great. Both formats preserve your color customizations and maintain full QR code functionality.

No registration required! QR Kit is completely free to use without creating an account, providing an email address, or filling out any forms. Simply visit the site and start generating QR codes immediately. There are no usage limits, no premium tiers, and no hidden costs. We believe in providing a straightforward, accessible tool that respects your time and privacy. You can generate unlimited QR codes, download them in multiple formats, and use them for any purpose—commercial or personal—without restrictions.

Yes, once you've generated and downloaded a QR code, it works completely offline. The QR code itself is just an image file (SVG or PNG) that contains your encoded information. It doesn't require an internet connection to be scanned. When someone scans your QR code with their smartphone, the device reads the encoded data directly from the visual pattern—no server lookup or internet connection is needed. This makes QR codes extremely reliable for environments with poor or no connectivity. Note that if your QR code contains a URL, the person scanning will need internet to visit that website, but the QR code scanning process itself works offline.

No limits whatsoever. Generate as many QR codes as you need, customize them freely, and download them in any format. There are no daily limits, no maximum number of QR codes per user, and no restrictions on commercial use. Whether you're creating one QR code for a personal project or hundreds for a business campaign, QR Kit handles it all for free. The only practical limitation is your browser's memory, which can easily handle thousands of QR codes without issue.

Nearly all modern smartphones can scan QR codes using their built-in camera apps without additional software. iOS devices (iPhone, iPad) with iOS 11 or later have native QR code scanning built into the Camera app. Android devices running Android 9 (Pie) or later typically include QR code scanning in the default camera app, though this varies by manufacturer. Many Android devices running older versions can scan QR codes through Google Lens or dedicated QR scanner apps available for free in the Google Play Store. Additionally, many tablets, some laptops with webcams, and dedicated barcode scanners support QR code recognition.

After generating your QR code, the easiest way to test it is to scan it with your smartphone camera. On iPhone, open the Camera app and point it at the QR code displayed on your computer screen—a notification will appear at the top if the code is recognized. On Android, open your camera app or Google Lens and point it at the code. For URL QR codes, verify the link opens correctly. For Wi-Fi codes, check that your device offers to connect to the network. For vCard codes, confirm that all contact fields are populated correctly when you preview adding the contact. It's good practice to test QR codes with multiple devices (both iOS and Android) before printing or distributing them widely.

Absolutely! QR codes generated with QR Kit can be used for any purpose, including commercial applications. Use them on product packaging, marketing materials, business cards, restaurant menus, retail signage, event tickets, or anywhere else you need to share information quickly. There are no licensing fees, attribution requirements, or usage restrictions. QR codes themselves are an open standard—no one owns the technology, so you're free to use them however you need. Whether you're a small business owner, marketer, event organizer, or enterprise corporation, you can use QR Kit for all your QR code needs.
