The images are being compressed when uploaded which is expected behavior, in fact, every image compression algorithm will lower the image quality.
However, this should not result in blurry/highly pixelated images if you use the right settings. Refer to the article Recommended Image Dimensions and Aspect Ratio to have the optimal solution.
