Understanding Image Resizing
Image resizing involves changing the dimensions of an image, either by increasing or decreasing its width and height. This process is crucial for several reasons:
- Optimizing Load Times: Large images can slow down web pages and digital presentations. Resizing images can reduce file sizes, leading to faster load times.
- Maintaining Quality: Proper resizing ensures that images maintain their quality and do not become pixelated or distorted.
- Fitting Specific Dimensions: Different platforms and applications require images to be of specific dimensions. Resizing helps meet these requirements.
