Merge Two Photos result

Put Two Pictures in One Frame

To merge two photos here means placing them next to each other, or one above the other, inside a single image. Each photo stays whole; nothing is blended, cut out or redrawn.

You get the pair as one file you can post, email or paste into a document, instead of two attachments that arrive in the wrong order. Add up to six photos, and from the third one a grid layout is available.

Set the spacing, a border and a background color, or leave the background transparent. Then save as JPG, PNG or WebP.

How to Merge Two Photos Into One Image

  1. 1

    Add and order your photos

    Click or drop two photos to start; you can add more later, up to six. Drag them or use the arrows to put them in the order you want, left to right or top to bottom.

  2. 2

    Pick the layout and size

    Choose side by side or stacked. Same height or same width scales every photo to the largest one; original sizes keeps each photo as it is. Then set alignment, spacing and border from 0 to 200 px, and the background.

  3. 3

    Download one image

    Press Merge Photos and check the preview, which shows in a fraction of a second in our test. Then save as JPG, PNG or WebP.

Where a Merged Photo Comes in Handy

Before and after

When you merge two photos for a renovation, a haircut or a retouch, a thin white or black border makes the dividing line clear, so nobody has to guess which half is which.

Product comparisons

Put two colors or two angles of the same item next to each other for a listing or a message to a buyer.

Screenshot pairs

Stack two screenshots into one tall image for a support reply or a how-to, instead of sending two files.

One-post collages

Place two pictures from the same day in one image so a post or a chat shows them together.

Side-by-side choices

Line up two options, such as two outfits or two paint swatches, and send one image to ask which one wins.

Documents and slides

Join a portrait and a landscape shot into one picture for a slide, a form or a printed page.

Listings and sale posts

Show the front and the back of an item you sell as a single picture, so a listing with one photo slot still tells the whole story.

Progress updates

Pair this month's photo with last month's for a fitness, garden or craft log, and keep the same height so the two line up.

Before You Merge Two Photos

  • Nothing is uploaded

    The photos are decoded and merged in your browser and never leave your device. The tool is free to use, with no sign-up and no limit on how many times you run it.

  • Size limits

    The merged image is capped at 16384 px on a side and 100 megapixels, and is scaled down with a note when it would be larger. Same height or same width may enlarge the smaller photo, so it can look softer.

  • What we measured

    On a Mac in Chrome, a 4000 × 5333 and a 3000 × 4000 photo merged side by side into 8000 × 5333 and saved as a 3.0 MB JPG in 0.4 seconds. The same pair stacked as PNG came out at 4000 × 10666 and 24.2 MB. Your device will differ.

  • It places, it does not blend

    This tool arranges photos in a frame. It does not fade one into another or put a person from one photo into another scene.

Frequently asked questions

No. The photos are processed in your browser and never leave your device.

Add both photos, choose side by side or stacked, set spacing and background if you want, press Merge Photos and download the result. Reorder them first by dragging.

JPG, PNG or WebP. JPG gives a much smaller file than PNG; PNG keeps a transparent background. In our test a stacked PNG of two large photos came out at 24.2 MB.

Up to 16384 px on a side and 100 megapixels. Larger results are scaled down to fit, and the tool tells you when that happens. A very large pair also gives a large PNG, so JPG is the lighter choice.

Yes, up to six. From three photos you can also choose a grid and set how many photos go in each row.

Yes. There is no sign-up, no watermark and no limit on how many times you use it.

No. It places whole photos next to each other in one image. Blending needs an AI editor, and this tool does not use one.

Pick same height (side by side) or same width (stacked) to scale them to match, or original sizes to keep each as it is and set the alignment.

Yes. Choose side by side with same height, set the spacing to a few pixels and give it a white or black border so the two halves read as a pair.

The photos are drawn into the frame as they are, but same height or same width enlarges the smaller one, which can look softer. Pick original sizes to avoid that, and PNG to avoid JPG compression.

On iPhone and iPad Safari the merged image is capped at 16.7 megapixels. A larger result is scaled down to fit, and the tool shows a note.
