What Is an Image Resizer?
An Image Resizer is a utility that changes the dimensions of an image by increasing or decreasing its width and height. Resizing helps optimize images for different devices, websites, applications, and platforms without requiring professional photo editing software.
Unlike cropping, resizing adjusts the overall dimensions of the entire image while keeping all visible content intact. When the aspect ratio is maintained, the image remains proportionally scaled without distortion.
Why Use an Image Resizer?
Different websites and applications require images of specific sizes. Large images increase loading times and consume more storage, while oversized files may exceed upload limits. Resizing images helps improve website performance, reduce file size, and ensure compatibility across platforms.
