Need of Image Resizer

We all know that images captured by digital cameras and smartphones can be very large and sometimes it is necessary to change the file size of the images. For example, you may need to resize an image in order to email it or upload it to a website. While filling the application form, there is a fixed image size given accordingly we need to decrease or increase the photo size.

When viewing or sharing images online, it is often necessary to resize them or change the file size so that they fit perfectly on the viewer's screen. You may need to reduce the size of your images.

Now it's important to understand how to resize photos without losing quality. Technically, resizing changes the underlying pixel information. For example, reducing the width and height of an image removes all unnecessary pixel information. In order to enlarge the image, the image resizer has to add new pixels based on the original ones, so the photo looks blurry. So the essence of resizing an image without losing quality is taking it at the highest resolution and scaling it down.

There are two ways of resizing the image

One option is to compress the image. This allows you to reduce the file size without changing the size. Losing data by increasing compression reduces image quality.

Another option is to resize the photo to reduce the number of pixels required to store the image. Reducing the image size does not reduce image quality, but may result in loss of detail. Photos taken by modern cell phones and cameras are typically over 6 million pixels, while most cell phone, tablet, notebook or TV screens are only about 1.5 million pixels. screen). When you print it, and if you resize your image, decreasing its width and height to half, your image will have about the same number of pixels as the screens that will display it.
