For eCommerce retailers, image resizing is an obligate issue. Because they have the only way to make a trade-in their online store with customers and that is an image.

Images are the main stuff of an eCommerce business. Ecommerce retailers used many photo retouching, resizing to make their images better attractive to catch customers’ attention.

Also resizing gives their product images a better file size for faster loading in the user screen.

To make the image file smaller

Resizing is used to make a bigger file size smaller for others using purpose.

Images that are bigger in their file size, make problems when using in the online upload. For instance, we all use social media platforms and upload many photos to make our day. But some video or image files can’t be uploaded to our social media profile because of their file size.

That is the issue to make images smaller in their file size. Also, for blog and web images, they must have to form in a way that isn’t taking too much time for loading. Loading problem causes for the greater file size of the image, then image resizing helps those images to keep their file size short.

What is the aspect ratio?

For example, a 6×4-inch image has an aspect ratio of 3:2 the measurement remains the same for all types of measurement scales.

The aspect ratio for a different image comes with different numbers like,

        1.85.1 and 2.39.1 for film photography

        4.3 and 16.9 for television, presentation slides, computer monitors, digital camera

        3.2 for camera photography

Pixel dimension

Pixels dimension means the total number of pixels in a row that consists of a picture. We are familiar with the word with resolution. We used it to describe our picture quality, which means the high-resolution picture is a thing of higher quality.

Resolution is counted as the fineness of a picture, the more pixels per inch the greater the resolution.

Pixels are actually square-based dot that is thought of as the smallest component of the raster image. Pixels are so small units as they used to count with a bigger unit that is called (mega). When we say three-megapixel that means it has three million megapixels.

Image dimension can be measured in any unit but in most cases, it is called pixels as the measurement unit of image dimension and inches for print images.
