How merging images works
Merge Images composites two or more pictures onto a single HTML canvas entirely in your browser — nothing is uploaded anywhere. Choose side by side to place images left-to-right, stacked to place them top-to-bottom, or overlay to layer them directly on top of each other with an adjustable opacity slider (handy for comparing two versions of an image or creating a ghosted double-exposure effect). Reorder images with the up/down arrows before merging — order matters for side-by-side/stacked placement and determines which image is the base layer in overlay mode. The result can be exported as PNG (with transparency), JPEG, or WebP. For combining images into a single scrollable strip after merging, or resizing the output afterward, try the Image Resizer.
