Frequently Asked Questions
How does this online QR scanner work without an app?
Our scanner utilizes modern web APIs (HTML5 Canvas and MediaDevices) to capture camera video frames and process pixel matrix data locally in your browser memory using computer vision algorithms.
Is my camera feed or uploaded image stored on a server?
No. All scanning and image processing take place entirely on your device. No images, video frames, or decoded payload data are ever sent to remote servers.

We support all standard web image formats including PNG, JPG, JPEG, WebP, GIF, and SVG files up to 10MB.
