Frequently Asked Questions
- Can I scan a QR code with my camera in the browser?
- Yes. ToolMint's QR Code Scanner supports live camera scanning on compatible browsers using getUserMedia and BarcodeDetector. It prefers the environment-facing camera when available.
- Can I upload an image instead of using the camera?
- Yes. You can upload PNG, JPG, or WEBP files. The tool then tries multiple detection methods, including direct image, canvas, and scaled canvas processing, to improve success rates.
- Does the scanner upload my image or camera feed to a server?
- No. The scanner processes QR codes locally in your browser. It uses built-in web APIs and does not need to upload the image or video feed to a server to decode results.
- What happens if the scanned QR code contains a link?
- The tool detects URL-like results automatically so you can identify links easily after scanning. You can also copy the result directly to the clipboard with one click.
- Why might scanning fail on some browsers?
- The scanner relies on BarcodeDetector support, which is strongest in Chromium-based browsers such as Chrome and Edge. Older or unsupported browsers may not expose the necessary APIs for camera or QR decoding.
