  1. 1

    Drop 2–8 images onto the box or tap to choose them. Use the ◀ ▶ arrows under the thumbnails to set the order.

  4. 4

    Press ⬇️ Download as JPG, PNG or WebP. No watermark, no size cap from us.

💡 Tip: Joining screenshots of a chat? Choose Stacked, spacing 0 and PNG so the text stays razor sharp.

Join images without an app or an upload

This is the plain, fast way to combine pictures into one file: two screenshots side by side for a bug report, a before-and-after stacked for Instagram, four product photos in a grid for a listing, eight holiday shots as a collage. Everything is drawn on a canvas inside your browser, so it works offline and your photos are never uploaded.

  • Horizontal (side by side) keeps every image the same height.
  • Vertical (stacked) keeps every image the same width — ideal for long chat screenshots.
  • Grid and Auto collage balance mixed sizes automatically.
  • Spacing 0 gives a seamless join; add spacing and rounded corners for a collage look.

When you want them merged, not joined

An image joiner places pictures next to each other. If what you actually want is one photo — two people who were never in the same room standing together, a friend added to the group shot — that is AI blending, and it lives on the AI Photo Merger and Two People in One Photo pages. Same site, one free AI blend a day.

Frequently asked questions

How do I merge two images into one online for free?

Drop both images into the joiner above, choose Side by side or Stacked, and press Join. Download the result as JPG, PNG or WebP — free, no watermark, and nothing is uploaded.

Can I join images vertically?

Yes — choose Stacked (vertical). Every image is scaled to the same width and placed one under the other, which is perfect for long chat screenshots.

Does it reduce quality?

You control the output width (up to 4096 px) and format. Choose PNG for screenshots and text; JPG or WebP for photos.

How many images can I combine?

Up to eight per join. For a long series, join in batches and then join the results.

Is it really free and private?

Yes. The joiner runs entirely in your browser — your images never leave your device — and there is no watermark, signup or limit.
