Image Joiner

Combine two or more images side by side, or stacked — free, instant, entirely on your device.

How to join images together

Drop two or more images into the box above in the order you want them joined, choose side-by-side or stacked layout, and the combined image updates live — download it whenever it looks right.

For example, a before-and-after comparison pair works well side by side, while a step-by-step sequence of screenshots often reads more clearly stacked vertically.

How images of different sizes are handled

Each image keeps its own aspect ratio and is scaled to match the shared height (side by side) or width (stacked) of the combined canvas, so nothing gets stretched or distorted regardless of the original dimensions.

When to combine instead of collage

Combining images side by side works best for a small, deliberate set of photos meant to be compared directly — a before-and-after pair, two product angles shown together, or a handful of screenshots that need to be read in sequence. It keeps every image at full size in a single row or column rather than arranging them into a decorative grid.

If you're working with more than a few images, or want a more visually varied layout with different-sized tiles, the Photo Collage Maker is the better fit — it's built specifically for arranging a larger set of photos into a single grid-style graphic rather than a simple strip.

Keeping every image aligned

When images of different heights or widths are combined, this tool aligns them along a shared edge so the result doesn't look staggered or uneven — worth cropping your source images to matching proportions beforehand if a perfectly uniform grid matters for your use case.

The combination itself runs through the Canvas API directly in your browser, drawing each image onto one shared canvas in sequence — no server processing is involved, so the result appears as soon as your images are loaded.

Getting a clean before-and-after

For a before-and-after comparison specifically, cropping both photos to the same framing beforehand makes the combined result read much more clearly than two images shot from slightly different angles or distances — the closer the framing matches, the more obvious the actual change becomes to anyone viewing it.
