What is Image Size?
Image size refers to the amount of data in a digital image and its pixel dimensions.
Pixel Dimensions
Pixel dimensions are the width and height of an image measured in pixels, such as 4032 × 3024 px.
File Size
File size tells you how much storage space the image uses, typically shown in KB or MB.
Megapixels
Megapixels indicate the total number of pixels in an image. A higher megapixel count usually means more image detail.
Image Format
Image format such as JPG, PNG or WebP determines how an image is compressed and stored, affecting compatibility, quality and file size.
