Combine images
To combine images is to join several photos into one picture: side by side, stacked or in a grid. Choose the images, set the order and save, all in your browser with nothing uploaded. The images are not cropped and keep their full resolution.

How it is calculated
In short: the tool places your images on one common canvas, side by side, stacked or in a grid, with or without gaps. Unlike a collage nothing is cut off: every image appears in full.
How it works
- Drop two to twelve images, choose them or paste with Ctrl + V.
- Pick the arrangement: side by side, stacked or a grid with 1 to 6 columns.
- Adjust the order with the arrows, then set spacing, margin and background.
- Choose a format and click “Combine and save images”.
Matching sizes
- To the smallest image: all images get the same height (side by side) or width (stacked) as the smallest. Larger images are reduced, nothing is scaled up.
- To the largest image: smaller images are enlarged, which can look soft.
- Keep original sizes: nothing is scaled. Images of different sizes are aligned centred, top or bottom (left or right).
Honest limits
- The result is capped at your browser’s pixel limit (50 megapixels, 16.7 megapixels on iPhone and iPad). If it is exceeded the tool scales everything down evenly and tells you.
- Transparency exists only in PNG and WebP; with JPG the background becomes white.
- To turn images into a PDF use “Images to PDF” instead.
Privacy
The images are processed only in your browser and are not uploaded.
Frequently asked questions
How can I combine images?
Choose or drop the images, pick the arrangement (side by side, stacked, grid), check the order and click “Combine and save images”.
Are the images cropped?
No. Every image appears in full. If the aspect ratios differ, empty areas in the background colour appear, depending on alignment.
How do I change the order?
Below each image there are arrows to move it earlier or later. The preview updates immediately.
Can I choose a transparent background?
Yes, with the “Transparent” option and the PNG or WebP format. JPG cannot store transparency, so its background becomes white.
How large can the result be?
Up to 50 megapixels, up to 16.7 megapixels on iPhone and iPad. If the result is larger, the tool scales all images down evenly.
Are my images uploaded?
No. Combining runs entirely in your browser; the images never leave your device.
