Reshade is a powerful tool that lets you zoom in on images without losing quality. The program can be used by both experienced and novice users.
As soon as you open the image (unfortunately, "drag and drop" is not supported), two copies of it will be displayed - the original and the modified one.
First of all, you can adjust the image size (height, width and resolution), or choose the screen resolution (from 100x100 pixels to 6000x3750);
With Reshade you can adjust noise levels and remove artifacts from the image. You can use the Selection Tool to trim an area of an image to its edges. It is possible to adjust the compression quality. In order to quickly process many images, you can use batch editing of images.
