How to Crop Multiple Images to the Same Size Online

Why identical dimensions are not enough

Two files can both be 1080 × 1350 pixels and still look inconsistent. The face may be larger in one image, the product may sit farther left, or one photo may include much more empty background.

A reliable workflow must match both the final dimensions and the composition inside the frame.

• Move every image independently.
• Use a separate zoom value for each layer.
• Compare layers with adjustable opacity.
• Export every result with one shared ratio and pixel size.

Upload source images with different sizes

Open the Overlay Crop editor and upload up to five JPG, PNG, or WebP images. The source files may have different resolutions, orientations, and aspect ratios.

Each photo becomes a separate layer, so changing one layer does not move or resize the others. The files are processed locally in the browser rather than uploaded to the editing server.

Choose one final aspect ratio and output size

Select the ratio required by the destination. Common choices include 1:1 for square layouts, 4:5 for portrait social posts, 9:16 for vertical video, and 16:9 for wide content.

Then enter the final width and height. For example, choosing 1080 × 1350 makes every exported image exactly 1080 pixels wide and 1350 pixels high.

Adjust every photo independently

Select the first layer and place the subject where it should appear inside the crop frame. Adjust the zoom until the subject has the desired visual size.

Repeat the process for every remaining layer. This compensates for differences in camera distance and original framing without forcing all photos to use identical source coordinates.

Use opacity to match the composition

Reduce the opacity of the upper layer to about 40–60 percent. You can then see the reference image and the selected image at the same time.

Align stable landmarks such as eyes, face outlines, product corners, horizon lines, or background edges. Restore opacity to 100 percent after the layers match.

Export a consistent image set

Check every layer separately, then download individual files or export all results as a ZIP archive. Every output uses the same aspect ratio and dimensions while preserving the position and zoom chosen for that layer.

A small original can still be exported at a large size, but heavy enlargement may reduce sharpness. Use source files at least as large as the intended output whenever possible.

Useful applications

This workflow is useful whenever several images must look consistent as a set.

• Before-and-after retouching comparisons
• Product catalog photos
• Profile and staff portraits
• Social media carousels
• Progress photos
• Photo restoration examples
• Thumbnails and presentation slides
