Online QR Code Scanner Tool

What can QR codes contain?

QR (Quick Response) codes are two-dimensional barcodes that can store significantly more data than standard linear barcodes. While most people encounter them as links to websites, they can store various types of information:

• Website URLs: Links to menus, payment portals, or social media.
• Wi-Fi Credentials: SSID, security type, and passwords to join networks.
• Contact Information: vCards or MECARDs containing names, phones, and emails.
• Plain Text: Any alphanumeric message or identifier.
• App Actions: Pre-filled emails, SMS messages, or phone numbers.

QR Safety: Why we ask before opening

Scanning a QR code is functionally equivalent to typing a URL or performing an action. Because malicious QR codes can lead to phishing sites or trigger unwanted actions, Online Barcode Scan prioritizes your safety:

• Confirmation First: We never open a link or trigger an action automatically. You must confirm every action after reviewing the decoded content.
• Scheme Blocking: Our scanner automatically blocks potentially dangerous executable schemes like javascript: to prevent browser-based attacks.
• Wi-Fi Privacy: While we decode Wi-Fi passwords for your convenience, we cannot (and will not) automatically connect your device to any network.

How to scan QR codes on a laptop or desktop

Unlike mobile phones with built-in camera apps, scanning a QR code on a computer often requires a specialized tool. With this tool, you can scan in two ways:

1. Using your Webcam: Click "Use Camera" to turn your webcam into a scanner. Hold the QR code (on your phone or a piece of paper) up to the lens.
2. Scanning a Screenshot/Image: If you see a QR code on your screen, take a screenshot and upload it here. The scanner will decode it instantly without needing a camera.
