Scale To Fill is a free iPhone app developed by Vitalij Schaefer that allows users to resize images to different sizes without cropping or adding borders. With this app, users can easily adjust the aspect ratio of their images, although it should be noted that resizing may result in some distortion.

One of the key features of Scale To Fill is its ability to resize images without cropping. This means that users can maintain the original composition of their images while adjusting the size. However, it's important to keep in mind that resizing an image to a different aspect ratio may result in some compression or stretching, which can cause distortion.

While Scale To Fill may not be suitable for photographs with people, animals, or objects due to the potential for distortion, it can be a handy tool for resizing landscape photographs, backgrounds, real estate photos, or drawings. It provides a quick and convenient way to adjust the size of images without the need for complex editing software.

Overall, Scale To Fill is a straightforward and user-friendly app for resizing images on your iPhone. It offers a simple solution for adjusting the aspect ratio of your images without cropping or adding borders.
