How to use it
- Add two or more images and arrange them with the arrows.
- Choose side by side, stacked, or a grid, and set the gap and background.
- Check the preview and download.
Match sizes, or not
With Match sizes on, pictures placed side by side are scaled to the same height, and stacked pictures to the same width. That gives clean edges with no ragged gaps, and it is almost always what you want for comparisons. Turn it off to keep each image at its real pixel size, which is useful when the difference in size is itself the point.
Ideas
- Before and after: two photos side by side with a small gap.
- Long screenshots: stack several phone screenshots into one tall image for a conversation or a set of instructions.
- Contact sheets: a grid of photos from an event, to send as one file.
- Receipts: a grid of receipt photos for an expense claim. For a multi-page document instead, try JPG to PDF.
Keeping the result a sensible size
Combining full-resolution phone photos produces a very large image quickly: four 12-megapixel photos side by side are over 16,000 pixels wide. That is more than any screen can show, and too big for many upload forms. If the result is going online, resize it to 2000 to 3000 pixels on the long side, or resize the photos before combining them.
Very large combinations are scaled down to stay within what browsers can draw, at most 16,000 pixels on the longest side, and less on iPhones and iPads.
Questions people ask
