About Image Merger

The Image Merger combines several images into one — side by side, stacked, or in a grid — with spacing and a background. It is for assembling collages, comparisons, or composite images.

Combining images in an editor is more work than the task needs. Merging them locally with simple layout options is quick and keeps the images private.
