How to Change Image Size by 3 Online Photo Editors?

What Does Photo Size Mean?

In a nutshell, the photo size pertains to the height and width of an image in pixels. It also represents a photo’s resolution which can be measured by pixels. For example, a 30- megapixel (MP) camera takes pictures with 4480×6720 pixel dimensions. These dimensions make it possible to print up to 30×45 sizes in excellent condition. When it comes to photo size, it’s important to remember that the higher the image setting, the larger the picture and file size.

Why Change the Photo Size?

There are various reasons why your photo would need resizing. The first is that it needs to be printed in a particular size that is different from its original size. Second, there are certain parts of your photo that need to be cut off or cropped. Some photos have irregular edges or irregular parts that need to be rid of, and resizing the image is one solution for that.
