Image Combiner
Combine several images into one — side by side or stacked — as a single file.
Putting images together
There are plenty of reasons to merge images into one: a before-and-after pair shown together, a comparison of options, a simple strip of photos, or stitching screenshots that were captured separately into one tall image. Rather than paste them into a document, this joins them directly into a single picture you can share or upload as one file.
Arrange them horizontally for a row or vertically for a column, and they are combined edge to edge into one image.
Keeping it tidy
Combined images look best when the pieces share something — the same width when stacking, the same height when placing side by side — so nothing has to be awkwardly scaled. If your images are different sizes, resizing them to match first gives a cleaner, more even result.
How to combine images into one
- Add the images you want joined.
- Choose whether to stack them vertically or place them side by side.
- Download the single combined picture.
One file instead of five
Combining is the quick way to show a sequence — before and after, a set of screenshots, a step-by-step — as a single image that cannot arrive out of order or half-loaded. Anywhere that only accepts one attachment, joining first solves the problem.
Images of matching width stack most cleanly. If yours differ a lot, resize them to a common width first so the result does not have awkward gaps or a stepped edge.
Frequently asked questions
Can I combine images of different sizes?
Yes, though matching their width or height first gives a much tidier result.
Vertical or horizontal — which should I choose?
Vertical suits step-by-step sequences and screenshots; horizontal suits before-and-after comparisons.
Is there a limit on how many I can join?
No fixed limit, but very long strips become unwieldy to view.
Can I stack images vertically as well as side by side?
Yes. Combine them in a row or a column, whichever suits what you are showing.
How many images can I combine?
Several at once — enough for a comparison strip or a set of stitched screenshots.
Is anything uploaded?
No. The images are combined in your browser and never sent to a server.
