Image resizer is a software or tool used to change the size of digital images, either to make them smaller or larger. Resizing an image can be useful when you want to fit an image into a specific frame or to reduce its file size.
There are several image resizer tools available, including free online tools such as PicResize, Bulk Resize Photos, and ResizePixel, as well as more advanced software like Adobe Photoshop, GIMP, and Lightroom.
To resize an image, you need to open the image in the image resizer tool and specify the new dimensions of the image. You can choose to resize the image by pixels, percentage, or by a specific size in inches or centimeters. You can also choose to maintain the aspect ratio of the image, which means that the width and height of the image are scaled proportionally.
It's important to keep in mind that resizing an image can affect its quality, especially when enlarging an image beyond its original size. Therefore, it's recommended to choose an image resizer tool that uses high-quality interpolation algorithms to minimize the loss of quality.
