What Is Our Merge Images Tool?

Merge images tool joining two photos side by side

Our Merge Images tool is a free online tool that lets you merge images into one file. With Merge Images you pick how the photos line up. Horizontal puts them side by side into one wide image. Vertical stacks them top to bottom into one tall image. The original photos are not changed — Merge Images places them together and resizes them so the edges match. People merge images to compare two photos side by side, to turn a set of screenshots into one long image, or to combine several photos into one file that is easier to share.

Good For

Before-and-after comparisons, long screenshots, step-by-step guides, product shots in a row, and any time two or more photos need to become one file.

Horizontal vs Vertical

Horizontal joins your photos left to right into one wide image. It is the usual pick for a side-by-side comparison. Vertical stacks them top to bottom into one tall image. It is the usual pick for long screenshots or a set of steps.

Merge Images FAQ

Common questions about our online merge images tool

How do I merge images into one?

Open the Merge Images tool at the top of this page. Add your JPG, PNG, or WebP photos. The combined image appears in the preview right away. Pick Horizontal to place them side by side, or Vertical to stack them top to bottom. Then click Download. The photos merge in the order you add them, so add them in the order you want.

Can I merge more than two images?

Yes. Add as many photos as you need. Our Merge Images tool joins them all into one file, in the order you added them. Horizontal lines them up into one wide image. Vertical stacks them into one tall image. There is no limit and no sign-up.

What happens if my images are different sizes?

They line up on their own. For a horizontal merge, every photo is resized to the same height. For a vertical merge, they are resized to the same width. Each photo keeps its proportions. Nothing is cropped or stretched, and there are no gaps between them.

What is the difference between horizontal and vertical merge?

Horizontal places your photos side by side into one wide image. It is the usual choice for a before-and-after or a comparison. Vertical stacks them top to bottom into one tall image. It is the usual choice for long screenshots or a set of steps. You can switch between the two, and the preview updates right away.

Are my images uploaded to a server?

No. Your photos are not sent to our servers or to anyone else. The merging happens on your device, and the combined image stays there too. Once the page has loaded, Merge Images even works offline. That makes it a good fit for screenshots, personal photos, or anything you would rather keep private.

Is Merge Images free, with no sign-up or watermark?

Yes. It is free, with no account, no email, and no watermark on the merged image. There is no limit on how many photos you combine. Merge as many images as you like, as often as you like.

What image formats can I merge?

You can merge JPG, PNG, and WebP photos. You can even mix formats in the same merge. The combined image downloads as a PNG, so any see-through areas from your PNG files stay see-through.

Will merging reduce image quality?

Photos that are already the same size are placed into the merged file untouched. When sizes differ, the photos are resized to line up. Resizing changes them a little, the same as any time a photo is resized. The result downloads as a PNG, so nothing is re-compressed.
