I shot a bunch of crystal clear 8k images on my Nikon z7ii and printed some of them at Walmart. The size of the photo on my screen was 14”x20” and it looked super clear and sharp. I printed it off to an 8”x10” and the print wasn’t anywhere near as sharp. Any ideas? Do I need to find a better place to print?

I'm not looking to print anything fancy, just a batch of photos I took on my phone. However, when I upload them to the walmart website to print, they look as though they've all been compressed. This extends to when I open the edit menu to look at each photo individually, not just as thumbnails. I just want to know if anyone has had any experience with making online orders to walmart's photo centre, and if they do, whether they noticed this issue/if the apparent compression in the preview affected the final print at all?

EDIT: I'm in Canada, idk if the photo services are different between Walmart here and in the US

Image is just for attention. He I want to get photos printed off. I have no clue where to go locally or if I should just get them printed online and shipped. I think the largest is going to be 8x10 but most are 5x7, hard to remember all the frames I bought. Anyways thanks in advance.

I want to print out some photos at Walmart. They’re just vision board pictures, but I still feel awkward about knowing if someone sees the pictures I print out.

Do they? Or do they just get printed out and then automatically placed in envelopes?
