Quick collages without an app
Before and after pictures, a product from several angles, holiday highlights or a team overview: a collage tells it in one image. Choose a layout, and the photos fill their cells automatically; each picture is cropped from the center so there are no empty bars.
In the grid layout the last row stretches to the full width when the number of photos does not fill it, so the collage never has gaps.
Sizes that fit
Square and portrait posts use the sizes Instagram and other networks show best, stories are 1080 by 1920 pixels and A4 has 300 DPI for printing. Spacing and rounded corners scale with the size, so the look stays the same.
