How to combine images into one
- Choose two or more images. You can add more later.
- Pick Side by side, Stacked, or Grid, and put the pictures in the order you want.
- Set the scaling, spacing, alignment, and background color. The preview updates as you go.
- Choose PNG, JPG, or WebP and press Download.
For a clean row of photos with different shapes, scale to the same height and add a small gap. For a contact sheet, use Grid with the largest size so every cell is the same.
Questions
Are my images uploaded?
No. The pictures are joined on a canvas inside your browser tab and never leave your device.
Can I put pictures of different sizes together?
Yes. Choose "Smallest" or "Largest" under the scale option to bring them to the same height (side by side), width (stacked), or cell size (grid). "Keep sizes" leaves every picture at its own size and aligns it to the top, center, or bottom.
How big can the combined picture be?
Browsers limit canvas size. If the result would pass about 16,000 pixels on a side or 120 megapixels, it is scaled down to fit, and the result line under the preview tells you the final size.
Can I change the order or turn a picture?
Yes. Drag a thumbnail, or use its arrow buttons, to move it. The rotate buttons turn a picture a quarter turn at a time.
Which format should I save?
PNG keeps every pixel exactly and supports a transparent background. JPG gives much smaller files for photos. WebP is small and supports transparency too.
