Thanks to the dynamic QR code generator. Once a URL is shortened, the QR code can be accessed by simply adding /qr at the end of the shortened URL:
E.g http://mydomain.com/alias/qr
Different QR code sizes (max allowable size is 545 x 545) can be accessed by adding a size parameter at the end of the URL QR code:
http://mydomain.com/alias/qr/SIZE where SIZE = Pixel Dimensions
e.g https://weeurl.xyz/freesite/qr/400 (QR Code size at 400px by 400px)
e.g https://weeurl.xyz/freesite/qr/200 (QR Code size at 200px by 200px)
