Where can I get good graphics for the application?

Question

Android

Where do developers get high-quality graphics for their applications? Let's say there is an activity with the entrance to the application and there is a certain photo in the background. So here's what I'm getting at. In good applications, the background is perfect, no pixels or distortion are visible anywhere. No matter how much I searched on the Internet, everywhere in the images there are jambs and pixels are visible. Maybe there are sites where you can find high-quality graphics for the application? Or ways to improve an existing photo

Order from designers.
Sometimes you can search on sites where there are images in high resolution, but normal applications draw for themselves.

Answer 2

Pixels are visible because the background is in low resolution. If the current photo is in low resolution, then it cannot be improved.
There are free high resolution photos on Unsplash .
