Free Online QR Code Scanner — Read QR Codes from Images & Live Camera
MakeCard Free QR Code Scanner is a high-speed, 100% in-browser utility that lets you scan and decode any QR code without installing external apps or uploading files to remote servers. Whether you have an image file, a screenshot on your clipboard, a photo from WhatsApp, or want to use your device's live webcam or rear smartphone camera, this tool decodes the content in milliseconds. It automatically recognizes URLs, Wi-Fi credentials, digital business cards (vCard), UPI payments, emails, phone numbers, and coordinates, allowing you to copy, download, or interact with the decoded information securely.
How to Use QR Code Scanner
Choose your preferred scanning method: "Upload Image" (to drop a photo or paste a screenshot) or "Live Camera" (to scan in real time with your webcam or phone camera).
If scanning an image, drag and drop any PNG, JPG, or WebP file into the dropzone or press Ctrl+V to paste a screenshot directly from your clipboard.
If using the camera, click "Start Camera", grant browser permission, and optionally select between front or rear cameras on mobile devices.
Point the camera viewfinder at the QR code. The engine automatically detects the code and sounds a scan confirmation tone.
View your formatted results instantly with domain security validation, 1-click clipboard copy, vCard export, Wi-Fi password copy, or text file download.

Pro Tips for Best Results
- For live camera scanning, hold the QR code steady approximately 6 to 12 inches away from your lens so the autofocus can lock in.
- Ensure good ambient lighting. Harsh glare or dark shadows across the QR pattern can disrupt optical detection.
