OVERLAY CROP GUIDE
How to Crop Multiple Images to the Same Size
Updated June 19, 2026
Cropping several images one by one often creates small framing differences. A shared crop frame solves that problem by letting every image use the same output ratio and pixel size.
Why a shared crop frame matters
The same dimensions do not guarantee the same composition. A face can appear larger, a horizon can move, or the subject can drift between files. Overlaying the images makes those differences visible before export.
This is especially useful for retouching comparisons, product updates, progress photos, and social media carousels.
Step-by-step method
Upload up to five images, choose the target ratio, and set the output width and height. Select each layer, lower the opacity of the top image, then drag and zoom until the important landmarks match.
- Use eyes, corners, horizon lines, or fixed background objects as alignment points.
- Lock a layer after it is aligned.
- Export all files only after checking each layer at 100% opacity.
Avoid these common mistakes
Do not align only the outer edges of the files because different cameras may include different amounts of background. Align the subject first. Also avoid excessive enlargement when the original image is small, because the exported dimensions can be identical while visual sharpness is not.
Choose the right output size
For web use, choose the final publishing dimensions instead of exporting an unnecessarily huge file. A 1080 × 1350 pixel output is a practical 4:5 size for many social posts, while 1080 × 1080 works for square layouts.
FAQ
Will all exported images have the same resolution?
Yes. The selected output width and height are applied to every exported crop.
Are the original files modified?
No. New files are generated in your browser and the originals remain unchanged.
Overlay image crop editor
Upload your original and edited photos, lower the top image opacity, then align facial features or fixed background points. Every exported image uses the same crop ratio and pixel dimensions.
