Note: This decoder behaves as an average smartphone qrcode scanner
If you uploading a qrcode image file please ensure the image is in focus blurred or fuzzy qrcodes will not be decoded. Also ensure the area of the qrcode in the image is at least 60%. Tiny qrcodes in large images as well as partial qr images will not be decoded.
If you intend to use an URL then ensure it points directly to the image file, html files will not be accepted nor decoded. This scanner does not look forimages in webpages.
Example: https://jeroen.steeman.org will not work. What will work is https://jeroen.steeman.org/Images/QR-Code.png.
