Collage Maker

Cells use cover-fit: each photo scales to fill its cell completely and the overflow is cropped from the edges, which is what keeps grids looking clean instead of letterboxed. Put photos whose subject sits near the center into the smaller cells, and lead photos into the big cell of the 1+2 and 1+4 layouts. Swapping two photos is one click on each cell.

Square 1:1 (2048px) covers Instagram feed posts and profile grids; 4:5 portrait fills more screen in the feed and is what most photographers post; 9:16 is stories and TikTok. The canvases here render larger than any platform requires, so the platform downscales rather than stretches — the direction you want for sharpness.

JPG, almost always — for photographic content it looks identical at a fraction of the size, and every platform re-compresses to JPG-like formats anyway. PNG matters only if you need exact pixels (screenshots in cells, flat graphics) or plan further editing. If the JPG is still too big for a group chat, the image compressor squeezes it further.

The two side-by-side layout is exactly that — the standard format for cleaning results, renovations, and progress photos. Set spacing around 8–12px with a white background for the classic look. Resellers photographing restored items: shoot both photos from the same angle and distance, and the comparison sells itself.
