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

  1. Add the images you want joined.
  2. Choose whether to stack them vertically or place them side by side.
  3. 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.
