About Merge Images
Merge Images joins two or more pictures into a single file. Put photos side by side for a before-and-after comparison, stack them vertically to build one tall image, or stitch a series of phone screenshots into a long scrolling capture you can share in one go. You can combine up to 20 images at once, in any order.
The tool matches the images for you: with “Match smallest” every picture gets the same height (side by side) or the same width (stacked) without ever being upscaled, “Match largest” scales them up to the biggest one, and “Original sizes” keeps each image untouched with a top, middle or bottom alignment. Add a gap, outer padding, rounded corners, a thin border and a solid or transparent background, and the live preview shows the exact result with its final size and estimated file weight.
Everything happens in your browser: your images are never uploaded, and the tool is free. Download the merged picture at full resolution as PNG, JPG or WebP, or copy it straight to the clipboard to paste it into a chat or a document.
