Understanding image resolution
Image resolution describes how much pixel information an image contains. An image with 3840 × 2160 pixels contains more than eight million pixels, or approximately 8.29 megapixels.
Resolution is different from file size. Two images with identical pixel dimensions can have very different file sizes because of format, compression, color depth and image content.
