QR Encode allows anyone to generate various types of QR codes. You can export generated QR code in PNG or EPS format. QR Encode offers the ability to change the background and foreground colors of generated QR codes and more.
You can also export your generated QR code in PNG or EPS format. For Google Maps, there’s an embedded map by which you can search for a location to generate your Google Map QR code. Additional settings allow you to change the size and quality of your QR code.
