How to combine images into one
- Drop in two or more images, such as screenshots, photos, or scans. You can add more at any time.
- Choose a direction. Top → bottom makes one tall image (chat threads, long web pages, recipes). Left → right makes one wide strip (panorama pieces, product rows, comic panels).
- Choose what to match. In a vertical stack every image is scaled to the same width. In a horizontal strip, to the same height. Smallest never enlarges anything. Largest keeps the biggest image at full size. 1080px gives a predictable social-media size.
- Reorder by dragging thumbnails. Click a thumbnail to remove it.
- Add a gap and background if you want separators, then export.
Tips for stitching screenshots
- Use PNG for screenshots. Text and UI edges stay crisp. JPG blurs small text and adds artifacts around letters.
- Crop overlapping parts first. If consecutive screenshots repeat the same message or line, crop it out before stitching. The tool joins images edge to edge and doesn't detect overlaps.
- Match widths to "Smallest". Screenshots from one phone are already the same width, so nothing gets resized at all.
- Very long results are scaled down automatically. Browsers can't export canvases beyond about 16,384 px on a side or roughly 16.7 megapixels in total (the iPhone Safari limit). If your stack is longer than that, the export scales to fit, and the panel shows the final size before you download.

For two photos of the same scene, the Before and After Maker adds labels and a divider. For a balanced layout of many photos, use the Photo Collage Maker.
