AIAZHWhat Are QR Codes and Why Use Them?
QR codes are two-dimensional barcodes that store data like URLs, text, contact information, and Wi-Fi credentials. They are scanned by smartphone cameras and eliminate the need to type URLs or contact details manually. Our QR Generator creates custom codes, while our QR Scanner reads codes from uploaded images — both run entirely in your browser.
How to Generate QR Codes Online
Enter your data — a URL, text, or phone number — and our QR Generator creates a scannable QR code instantly. Customize the foreground color, background color, and add a logo in the center. Download the QR code as a PNG image for use on business cards, posters, product packaging, or digital displays.
How to Scan QR Codes from Images
Have a QR code image but do not know what it contains? Use our QR Scanner to upload the image and decode it instantly. The scanner reads QR codes from screenshots, photos, and downloaded images. It extracts the encoded data and displays it along with any embedded URL or contact information.
Use Cases for QR Codes
QR codes are used everywhere — restaurant menus, event tickets, product labels, business cards, museum exhibits, and marketing campaigns. Generate QR codes for your Wi-Fi network so guests can connect instantly. Create QR codes for your social media profiles, portfolio links, or payment pages.
Privacy-First QR Code Processing
Both generation and scanning happen locally in your browser. When you generate a QR code, the data is encoded on your device. When you scan a QR code from an image, the image is decoded on your device. Nothing is uploaded to any server, ensuring your data and scanned content remain completely private.
