How can we enlarge the QR code on Certificate?

[sachinb80]

After downloading the certificate the QR code is not getting scanned.
The QR code is blurred on the certificate and not getting scanned but when we enlarge the font or resolution it is working fine.
SO, CAN WE ENLARGE THE QR CODE ON THE CERTIFICATE? IF YES THEN HOW
This is the certificate pdf and screenshot

@ashokreddy1208 Yes we are able to scan the QR on certificate using any app but the problem is we need to enlarge the font of QR code then it is working.
Normal font is not getting scanned that we download after completing the course.
I have provided the sample certificate BASIC COURSE. Please download it and try scanning it
