How does the web scanner work?
Many people believe they need to download a sketchy third-party app to scan QR codes on their phone, which often leads to annoying ads and privacy issues.
Modern web browsers now allow websites to securely request access to your device camera. Once you grant permission, this web page streams the video feed locally. The Javascript engine in your browser constantly analyses the frames looking for the three distinct squares of a QR Code. Once found, it instantly extracts the embedded string and stops the camera. Because the video feed is processed completely inside your device, the camera stream is never uploaded or sent over the internet.
Frequently asked questions
Can I scan a barcode from an image on my phone?
Yes. If someone sent you a screenshot or image of a QR code, you can use the 'Upload Image' tab above to select the photo from your device. The scanner will read it from the file.
Is it safe to scan unknown QR codes?
Scanning a QR code simply reveals the text or website hidden inside the image pattern. However, you should always verify the URL before clicking 'Open Website' to ensure it does not go to a malicious or phishing site.
Are my camera feeds or images saved?
No. All camera processing and image decoding happens locally within your browser. 100% of the extraction is done client-side, meaning we never see or save your photos.
