Resize allows you to resize images. Reduction is done by pixel averaging, which gives much better quality than sub-sampling. The program allows you to resize a batch of images and also convert to JPEG. This is useful for creating thumbnails for web pages or resizing the frames for animated gifs. The resizing algorithm produces high quality images because it uses all available information from the source image. Most other image resizing software only use a small amount of information from the source image.

Can be used as an image viewer.
