How to Join Two Photos Into One Image Free (Side by Side or Stacked)

A photo joiner takes two or more separate images and merges them into a single picture. You choose the arrangement — side by side for a row, stacked for a tall image, or a grid for a small collage — and the tool lines the photos up neatly, adds any gap or background colour you want, and exports one combined image. It's the quickest way to make a before-and-after, a comparison, or a multi-photo share without learning an editor.

Open the Photo Joiner and you're done in under a minute:

1. Add your photos — drop in two or more images (JPG, PNG or WebP).
2. Pick a layout — side by side, stacked or grid, then set the gap and a background colour to frame them.
3. Download — click join and save the single combined image, ready to share or upload.

Because it's a genuinely free photo joiner, there's no watermark stamped on the result and no sign-up — and since everything runs on your device, your photos are never uploaded to a server.

A few small things make the join look professional rather than rough:

• Use photos of a similar size or orientation — two portraits or two landscapes line up far more evenly than a mix.
• Crop first if one image has extra space around the subject; the Crop Image tool trims them to a matching shape so heights and widths match.
• Add a small gap and a white or black background for a clean, framed look instead of two photos jammed edge to edge.

Once you've joined the images, you may need the final file at a particular size. If a website or form has a KB limit, run the result through the Image Compressor to bring it under the cap while keeping it clear. Need your photo and signature combined for an exam form instead of ordinary pictures? Use the dedicated Photo + Signature Combiner, which lays them out in the format those forms expect.
