How it works
How to merge images online
Merging pictures into one image file takes three steps with this free online image merger tool — no software to install, no account to create.
1Add your images<br>Drag and drop photos onto the image merger, click to browse, or paste a screenshot straight from your clipboard.
2Choose a layout<br>Combine images horizontally, stack them vertically, arrange a photo grid, or place them freely on a canvas. Adjust spacing, background, and corner rounding live in the image preview.
3Download one image<br>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
Merge images in a row, one next to the other — 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 images horizontally →
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 the image merger does 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.
