I'm looking for a Windows (desktop) software to place several pictures into a single one and it has to export the final high resolution result image to JPEG (at least).
I would like also the application to let me choose from different customizable layouts (such as 3 pictures, 4, 5, etc. in different combinations of width/height) and allow to crop an input picture or zoom it to make it fit into the selected layout cell.
I've found Snap Photo Collage on the Microsoft Store, but I would like something for Win32.
