Frequently Asked Questions

What barcode formats are supported?
The scanner supports Code128, Code39, EAN-13, EAN-8, UPC-A, UPC-E, Codabar, ITF, and QR codes.
Is camera access secure?
Yes. The video feed is processed locally in your browser. No camera data is ever transmitted to any server.
Does it work on mobile?
Yes. The scanner uses the rear-facing camera by default on mobile devices.
Can I scan from a screen?
Yes, though results are best with high brightness and a clean camera lens.
Why is my barcode not detected?
Make sure the barcode is clearly visible, well-lit, and not blurred. Simple black-on-white codes scan best.
What image formats are supported for upload?
PNG, JPEG, WebP, and other common browser-supported image formats.
Does the image upload send my images to a server?
No. All processing happens entirely in your browser using the html5-qrcode library. Your images are never uploaded to any server.
