QR Code Generator

A QR code is a two-dimensional barcode that can store hundreds of times more information than a traditional linear barcode. It was invented in 1994 by Denso Wave to track automotive parts, but today QR codes are everywhere: restaurant menus, payment terminals, event tickets, product packaging, and business cards. Their popularity surged because any modern smartphone can scan them instantly without special hardware.

Unlike a barcode, which stores data only horizontally, a QR code stores data both horizontally and vertically using a grid of dark and light squares. The three large squares in the corners help scanners orient the code, while smaller alignment and timing patterns ensure accurate decoding even at an angle or on a curved surface.

Using the generator above is straightforward. Type or paste the information you want to encode into the text area. You can enter a website URL, a phone number with a tel: prefix, a WiFi credentials string, plain text, or even a vCard contact block. Click one of the preset buttons (URL, WiFi, or Phone) to auto-fill a valid example, then replace it with your own details.

The QR code preview updates in real time as you type. Once you are happy with the result, click the download button to save a 300 × 300 pixel PNG image. Everything runs locally in your browser, so sensitive data such as WiFi passwords or contact details never leave your device.

Marketing: Add a QR code to flyers, posters, and packaging to send customers directly to a landing page, promotional video, or social profile. Use a unique shortened URL for each placement so you can measure which channel drives the most traffic.

Hospitality and retail: Cafes and restaurants use WiFi QR codes so guests connect without asking for passwords. Retailers link QR codes to product manuals, reviews, or loyalty program signups. Hotels place them in rooms for local recommendations and concierge services.

Events and tickets: Concerts, conferences, and airlines use QR codes for digital tickets and boarding passes. Scanners at entry gates validate the code in milliseconds, reducing queues and paper waste.

Personal sharing: Create a vCard QR code for your business card, a phone QR code for quick callbacks, or a payment QR code linked to your preferred service. If you need a dedicated contact-card code, try our vCard QR Code Generator.

Follow these guidelines to make sure every scan succeeds. Keep the foreground and background in high contrast — black modules on a white background are the gold standard. Leave a quiet zone of at least four empty modules around the code so scanners can find the edges. Test the code at the exact size it will be printed, and avoid placing it on highly reflective or curved surfaces. If you add a logo, keep it small and centered, and test scanning afterward because logos reduce error-correction capacity.

For long URLs, shorten the link first. The less data a QR code holds, the larger its individual modules remain, which improves scan distance and reliability. Finally, always scan your finished code with both iOS and Android devices before mass printing.
