A QR Code scanner reads the black-and-white square pattern and instantly takes you to the link or app embedded in it. On most smartphones, this functionality is built right into the native camera app (iOS or Android), which automatically detects and decodes a QR Code when you point your lens at it.
Alternatively, you can use a dedicated third-party scanning app or an online scanner in your browser. Once the code is captured—either live via camera or by uploading an image—the scanner interprets the pattern and delivers the result, whether that's opening a website, displaying text, saving a contact, adding an event to your calendar, or another action.
Before you scan, check these key elements to ensure a smooth, secure experience.
The code should be crisp with high contrast between dark modules and the background. Faded inks or low-resolution screens can prevent decoding.
Aim for at least a 2 cm × 2 cm code with a clear margin (quiet zone) around it. Crowded edges or overlapping graphics can interfere with the scanner.
Higher error correction allows the code to remain readable even if parts are obscured or damaged—look for professionally generated codes that specify this.
Only scan codes from trusted sources. If a code appears pasted over another, or leads to an unexpected URL (verify for HTTPS), proceed with caution.
Ensure adequate lighting and hold your device steady. Shiny or reflective surfaces, extreme angles, or glare can impede the camera's ability to read the code.

Yes. When you use our online scanner, the QR Code is decoded entirely in your browser—no scan image or data is sent to our servers. We never collect or store your scan data, device details, or location information.
However, a QR Code itself can point to a link that includes tracking parameters. In that case, once the scanner opens the URL, the destination server (i.e. the QR creator's analytics service) may record your visit, device type, or IP address. To keep your scans as private as possible:
By combining our local-only decoding with good scanning hygiene, you get both convenience and strong privacy protection.
Yes. Our scanner supports QR Codes in any language — including multilingual codes.
No, The QR Code Generator's scanner works directly in your browser — no downloads or installations needed.
