Merge Images

Join images into one picture

Combine multiple images in a horizontal strip, a vertical strip or a grid. Horizontal layouts use a shared height and vertical layouts use a shared width, preserving each image’s proportions. A grid uses your chosen column count and tile dimensions. Contain keeps the whole source inside a tile; Cover crops its edges to fill the tile.

Spacing and backgrounds

Set the gap between images and the padding around the complete layout. PNG and WebP can preserve a transparent background. JPG fills transparent areas with the selected background color. Source images are resized when needed, so enlarging a low-resolution image does not add detail.

Output and privacy

Preview the merged result and download PNG, JPG or WebP. WebP export includes the same local fallback used by the other image tools when the browser lacks a native encoder. Inputs stay on your device. Each source file is limited to 50 MB, combined file sizes to 250 MB and decoded memory to a safe budget. Large layouts automatically resize to fit 10,000 pixels per side and a 40-megapixel browser budget, preserving layout proportions. Fixed grids use the first images that fit. The selected count is shown, and dragging changes their order. Animated inputs become a still frame.
