How do I combine images side by side?

Upload your images, select horizontal mode, and they will be placed left to right. SnapOtter auto-matches heights so images of different sizes align cleanly. Drag to reorder.

Can I stitch images with different dimensions?

Yes. In horizontal mode, images are scaled to match the tallest image's height. In vertical mode, they are scaled to match the widest image's width. This ensures a seamless result without gaps.

Is there a limit on how many images I can stitch?

No hard limit. You can stitch dozens of images in a single operation. The output size is constrained by available memory, but typical use cases (10-50 images) are handled without issues.
