How it works

How to merge images online

Merging pictures into one file takes three steps — no software to install, no account to create.

1

Add your images

Drag and drop photos onto the tool, click to browse, or paste a screenshot straight from your clipboard.

2

Choose a layout

Combine images horizontally, stack them vertically, arrange a photo grid, or place them freely on a canvas. Adjust spacing, background, and rounded corners live.

3

Download one image

Export the merged result as PNG, JPG, or WebP at full resolution. The file is generated instantly on your device.

Four ways to merge

One image merger, every layout you need

Merge images horizontally

Place two or more pictures side by side in a row — perfect for before/after comparisons, product shots, and combining screenshots into one wide image. Heights are matched automatically so the row lines up cleanly.

Merge side by side →

Merge images vertically

Stack photos on top of each other into one tall image — ideal for stitching long chat screenshots, receipts, step-by-step instructions, or full-page captures into a single scrollable picture.

Stack images →

Make a photo grid

Combine multiple photos into a tidy grid collage — great for mood boards, product galleries, social posts, and photo dumps. Choose the number of columns and let the tool do the math.

Freestyle collage canvas

Need full control? Drop images on a blank canvas and drag them anywhere, resize with a scroll or a corner handle, and layer them to build a custom collage — then export it all as one image.

FAQ

Frequently asked questions

How do I merge two pictures into one?
Add both pictures by dragging them onto the tool above (or click to browse, or paste with Ctrl+V). Choose Horizontal to put them side by side or Vertical to stack them, adjust spacing and background, then hit Download — you get one merged image file.
Is this image merger really free?
Yes — completely free, no watermark, no signup, no hidden limits. The tool runs in your browser, so there are no server costs to pass on to you.

Up to 20 images per merge — in a row, a column, a grid, or freely arranged on the canvas.
