In horizontal mode each image is vertically centered, so mismatched heights still align nicely.
Align and finish
Use a white or black background for photos to blend seamlessly, or transparent if you'll drop the result onto a website background later. Finish with [Resize Image](/tools/resize-image) for the exact width your platform needs.

Frequently Asked Questions
Can I set the spacing between joined images?
Yes — a gap slider from 0 to 200px gives you tight joins or clean borders.
What if my images have different heights?
They're vertically centered against the tallest image, so the join stays tidy regardless.
Will horizontal joins work for panoramas?
Yes, as long as the photos share similar exposure. For seamless blending of overlapping shots, a dedicated panorama tool gives better results.
