Merge images horizontally — how it works
Merging images horizontally places them in a single row, left to right, to form one wide image. It is the go-to layout for before-and-after comparisons, product feature strips, comic-style panels and simple banners. The tool scales every image to a common height so the row lines up cleanly, then lets you drag each image to fine-tune its position.
For the cleanest result, use source images with similar heights (or let the tool scale them to match). If your images have very different aspect ratios, the grid layout may suit them better. You can switch layouts at any time without re-uploading.
Horizontal merge makes comparisons and strips read instantly left-to-right. The tool aligns everything to a common height for a clean row.
