Join images into one
Place several pictures side by side or on top of each other, for a before/after, a comic strip, a long screenshot or a collage, and export a single image.
Arrangement and cropping
Add up to 16 images, arrange them horizontally or vertically, and drag the seam between two pictures to change how much room each gets. Any picture can be cropped first, freely or to 1:1, 4:3, 3:4, 16:9 or 9:16, and only the part that is kept is joined; the original stays available, so it can be cropped again. Each picture can fill its cell or fit inside it, with the chosen crop position.

Do the images need the same size?
