Frequently Asked Questions

How many photos can I merge at once?

You can merge as many photos as your browser memory allows, typically 10-20 high-resolution images without issues. For very large batches, the tool may slow down depending on your device capabilities. The output image dimensions grow with each added photo, so consider your final use case when adding many images.

Can I merge photos of different sizes?

Yes, the tool automatically handles images of different dimensions. You can choose to resize all images to match the largest or smallest dimension, or maintain original proportions with padding. Horizontal layouts align images vertically, while vertical layouts align them horizontally for a clean result.

What is the best layout for before-and-after comparisons?

Horizontal side-by-side layout works best for before-and-after comparisons, placing the original on the left and the result on the right. Ensure both images are the same height for a clean join. Add minimal spacing between images so viewers can easily compare details across the boundary.
