Use this guide to understand the reason as to why a logo/image gets pixelated after creating and downloading the QR Code using Scanova QR Code Generator.
The exact reason of the above issue is that while designing the QR Code, if you have uploaded the logo in PNG or JPG format then the format of the logo will remain the same even in the vector export. This is why only the logo will pixelate when the size of the QR Code is increased.
However, to avoid this, it is advisable to upload your logo in higher-resolution if you're planning to export the QR Code in high-resolution. This will ensure that the logo does not pixelate when the QR Code size is increased.
