recommendPart 1: Difference between Image Resolution and Image Size You Should Know

Image resolution and image resizing are two different things. Managing the image resolution is related to file quality. When there is more pixel information, it will create a high-resolution image with excellent quality. The higher the resolution, the better the quality. You‘d be surprised that an image with a significantly smaller size can be of the best quality. Moreover, the image resolution is measured in megapixels, and the image size is calculated using megabytes.

Different from image enlarge or resizing, increasing photo resolution does not only change the size of the image but also increases the pixel count of pixels.
