Image scaling is the process of resizing a digital image to make it larger or smaller while maintaining its quality. This technique is commonly used in graphic design, web development, and photography to ensure images fit specific dimensions without losing clarity or becoming pixelated. There are two main types of image scaling: upscaling and downscaling. Upscaling increases the image size, which can sometimes lead to a loss of detail, while downscaling reduces the size, often preserving quality. Various algorithms, such as bilinear and bicubic, are used to achieve the best results during this process.
