What Does it Mean to Resize My Images or Photos?

Photos Resize involves a series of simple processes channeled toward adjusting or changing the dimensions of an image to a required or predetermined size. The image’s width and height are often adjusted (increase or decrease). 

For example, you may be required to use specific dimensions when uploading an image for an application. Assume the required dimensions for most tools are 35mm x 45mm; all you need to do is upload your image and resize it to the desired size. You’ll be done in seconds without sacrificing the image quality of the original photo. 

Types of Image Resize

When it comes to image resizing, two essential types are worthy of mention, they are; Scale Down Resizing and Scale Up Resizing. 

Scale Down Resizing means reducing the image’s dimension, whereas Scale Up Resizing involves increasing the photo’s dimension. 

The most common passport size photo measures 35mm x 45mm. For example, Australia, Singapore, Nigeria, Mexican, British printed passport photos requires 45 mm high by 35 mm wide photo not be cut down from a larger picture. However, there might be certain exceptions to the rule like Canada passport photo measures 5×7 cm. Thus, depending on the requirements, you may need to Scale up or Scale down your photo.

Why is It Necessary to Resize Images?

You may need to resize your image for a variety of reasons. But first, let’s look at the most common reasons you might encounter. These reasons are also applicable to passport photo requirements depending on the country. 

Certain web pages are designed to accommodate specific photo dimensions, and exceeding the set dimensions will prevent you from uploading your image for that important application you eagerly need to finish. With this requirement in place, resizing becomes necessary.

Furthermore, resizing an image is a great way to crash or reduce the file size of a photo while keeping the original quality. This advantage helps to minimize data usage and the time it takes for an image to load on a webpage. 

Finally, resizing an image improves its visual quality by changing its resolution or aspect ratio.
