QR code is blurry

I'm experiencing an issue with viewing QR codes in PDF files on my Apple device. When I open a PDF file using Apple's default applications, the QR code appears blurry. However, when I open the same file with third-party applications, the QR code is clear. The file also appears clear on Windows operating systems. I'm looking for a solution to make the QR codes appear clear when using Apple's default applications. The screenshot shows the Data-Matrix code, but the same with the qr-code. I see this problem on all my Apple devices: iPhone 13, MacBook Pro 2016. And on several recent operating systems.

No one disputes that the QR code is blurry. it has definitely been over-processed.


What I am trying to understand is, "EXACTLY what steps did you go through to get that file in its current condition."


For example, Did you take a screenshot to collect that download?


What is shown on web site documents is often already a .pdf file. If you download that pdf file DIRECTLY, using the download icon already on the screen, rather than first opening in Safari then downloading the screen, would it be any better?

I open the website of a state company and click the "download" button. The point is that the file itself is fine, if I forward it to Windows or open it in Chrome, then the QR code will be clear. But all native Apple programs blur it. That is, if a Windows user downloads a PDF file and then forwards it to MacOS, the code will also blur.
