Smilla Enlarger is a portable software program for the Windows operating system that can be used to enlarge photos. The results depend on the resolution and quality of the source photo and the resolution increase entered by the user. They do look pretty good on average though making Smillar Enlarger one of the few valid one-click solutions to enlarge photos.

The program basically works the following way. The user loads a photo into the software program. The photo will be displayed automatically on the left side of the interface. A suggested new resolution will be automatically selected and a zoomed in area of the source photo will be displayed on the right side. The target resolution of the enlarged photo can be changed by moving the zoom slider or by entering a value for the width and height manually.

It is possible to change the area that is being used for the preview to ensure that the most important areas of the photo display fine in the new resolution.

The controls at the bottom can be used to fine tune the enlarged photo further to increase the overall quality. The following five controls are available as sliders in the program: Sharpness, Flatness, PreSharpen, Dithering, DeNoise.

A click on the calculate button will start the photo conversion. The enlarged photo will be saved in the source directory by default. Smilla Enlarger (via Essential Freebies) is a great software program for users who want to enlarge some of their photos or images.
