The process behind image QR codes practically involves a combination of encoding and decoding. Embedding an image into a QR code transforms the content into a digital format which is encoded in the black-and-white matrix. This includes compressing the image data and merging it with the QR code's structural data. 

Once scanned using an application, the image data gets separated from the structural data providing instant access to the image.
