What is a QR Code?
A QR (Quick Response) code is a type of two-dimensional barcode invented in 1994 by Denso Wave, a Japanese automotive company. Unlike traditional barcodes that store data horizontally, QR codes store information both horizontally and vertically, allowing them to hold significantly more data.
QR codes can encode various types of information including:
- URLs: Direct users to websites, landing pages, or online resources
- Text: Plain text messages, instructions, or information
- Contact Information: vCard data for easy contact saving
- Wi-Fi Credentials: Network name and password for easy connection
- Payment Information: Cryptocurrency addresses or payment links
- Geographic Locations: Latitude and longitude coordinates
How to Use This Tool
- Enter Your Data: Type or paste your text or URL into the input field. This can be a website link, message, contact details, or any text you want to encode.
- Adjust Size: Use the slider to select your preferred QR code size (128px to 512px). Larger sizes are better for print materials or scanning from a distance.
- Choose Error Correction: Select an error correction level based on your needs. Higher levels create more resilient QR codes that can still be scanned even if partially damaged.
- Generate & Download: Your QR code generates automatically. Click "Download PNG" to save it, or "Copy Image" to copy it to your clipboard.
- Test It: Always test your QR code with multiple devices and scanning apps before publishing to ensure it works correctly.
