Frequently Asked Questions
Are my camera video feeds or uploaded images sent to any server?
Never. All scanning and barcode matrix decoding executes 100% locally in your web browser memory using client-side Web Workers and native BarcodeDetector APIs. Zero bytes are ever transmitted over the network.
Can I scan a QR code from a screenshot without a camera?
Yes! Switch to the "Upload Image" tab and drag-and-drop any PNG, JPEG, SVG, or WebP file. You can also simply press Ctrl+V (Cmd+V on Mac) anywhere on the page to paste a screenshot directly from your clipboard.
Can I switch between front and rear cameras on my phone?
Yes. On mobile devices with multiple lenses, the tool auto-detects rear (environment) and front (user selfie) cameras, providing a 1-click "Flip Camera" toggle and flashlight/torch controls.
