Part 1. What Is Resizing An Image

Before we proceed with the tools for resizing an image, it is best to learn about the basics of resizing images. Many are still puzzled about scaling, resizing, and compressing differences. These are methods used to change the size of an image. But there is a thin line between these terms. Hence, this section will define each term for clarification and help you identify which method you should employ. Continue reading and learn about these terms.

Scaling

Scaling is an image processing technique used for resizing a digital image. The primary purpose of this method has to do with the visual appearance of an image. It can change the size by reducing or increasing the image information on an image. There comes pixel replication or image zooming and subsampling done by interpolating between pixel values.

In other words, is it an image operation that alters the image appearance, where you can zoom and shrink the size of an image. Keep in mind that the resolution is not adjusted to suit the new size of the image when scaling. PIxels can appear pixelated because they are stretched. Perhaps it is not mainly used for resizing an image file.

Resizing

In image resizing, the pixel information is altered. That is especially true when reducing the size of the image. This process removes the unnecessary pixel information to resize the image size. Resizing may also involve enlarging a photo. Yet, it is worth noting that achieving a larger size than the original may result in blurry or pixelated-looking images.

It would be easier to downsize a photo than to enlarge it, as it will significantly impact the visual appearance of the photo.

Compressing

Image compression can also be applied when changing the picture size. It minimizes the image’s size in bytes while still preserving the quality of an image with decent and acceptable quality. This process reduces file size, allowing you to store more images.
