What is Combine Images?

Combine Images merges multiple images into a single image — side-by-side, stacked vertically, or arranged in a custom grid. Drag thumbnails to reorder, customize spacing and background color, choose an image fit strategy, and export in your preferred format.

It supersedes the older Collage tool with finer control over grid columns, image fit, and output formats.
