About this tool

A single combined image is far more useful than two separate attachments when the point is a comparison: before and after, two design options, a product from two angles, a damaged item next to its packaging. One file, one glance, no scrolling between windows.

Images are aligned to a common height when placed side by side, or a common width when stacked, so the strip looks deliberate rather than ragged. Add as many as you need — the order follows your file list.

What it's good for

  • Making a before-and-after comparison image.
  • Placing two design options next to each other for feedback.
  • Combining photos of an item from several angles.
  • Stacking chart images into one figure.
