Image Merger

ImageOffline-ready

Image Merger stitches two or more photos into a single image entirely in your browser. Choose side-by-side, vertical stack, or a two-column grid layout; drag to reorder; adjust spacing and background color; then preview or download as PNG, JPEG, or WebP. Nothing is uploaded — ideal for before/after collages, social carousels flattened to one file, and screenshot strips.

Your files and inputs stay in your browser — nothing is uploaded or stored.

Side-by-side aligns images to the tallest height; stacked aligns to the widest width; grid uses two columns left-to-right. For stability, images are capped at 16,384px per side and about 50 megapixels total (~50,000,000 pixels).
