If your source images have exact-size (or an integer-multiple size of the original) for placeholders, then choose "pixelated", otherwise choose "low" or "high", "medium" as smooth resizing quality

The image is scaled with the "nearest neighbor" or similar algorithm to the nearest integer multiple of the original image size, then uses smooth interpolation to bring the image to the final desired size

If your source images have Display P3 color profile embeded, then choose "Display P3"
