Open Merge Images OnlineWhy merge images together?
- - Compare two versions of the same photo (before/after)
- - Build product collages for marketplaces or portfolios
- - Stack screenshots into a single shareable image
- - Create side-by-side size or color comparisons
Merging keeps everything in one file — one email attachment, one upload, one share.
How to merge in seconds
- Open the [Merge Images tool](/tools/merge-images).
- Drop two or more images.
- Reorder them with the arrow buttons if needed.
- Choose side by side or stacked.
- Set the gap and background, then download.
Everything runs locally — your images are never uploaded.
Horizontal or vertical?
Side by side (horizontal) is best for comparisons and panoramas. Stacked (vertical) suits before/after shots and reading documents. With a transparent background you can drop the result onto any design later.

Frequently Asked Questions
Is merging images free?
Yes — completely free, unlimited images per merge, no account required.
Does merging reduce quality?
No. Images are placed pixel-for-pixel on the output canvas. Export as PNG to keep it lossless, or JPG for smaller files.
Can I merge images of different sizes?
Yes — each image is aligned to the shared edge; in horizontal mode all images share the tallest height, in vertical mode the widest width.
