montage

ImageMagick image montage tool. Tiles images into a customisable grid. More information: https://imagemagick.org/script/montage.php.

Tile images into a grid, automatically resizing images larger than the grid cell size:

montage {{image1.png}} {{image2.jpg}} {{imageN.png}} montage.jpg
Tile images into a grid, automatically calculating the grid cell size from the largest image:

montage {{image1.png}} {{image2.jpg}} {{imageN.png}} -geometry +0+0 montage.jpg
Set the grid cell size and resize images to fit it before tiling:

montage {{image1.png}} {{image2.jpg}} {{imageN.png}} -geometry 640x480+0+0 montage.jpg
Limit the number of rows and columns in the grid, causing input images to overflow into multiple output montages:

montage {{image1.png}} {{image2.jpg}} {{imageN.png}} -geometry +0+0 -tile 2x3 montage_%d.jpg
Resize and crop images to fill their grid cells before tiling:

montage {{image1.png}} {{image2.jpg}} {{imageN.png}} -geometry +0+0 -resize 640x480^ -gravity center -crop 640x480+0+0 montage.jpg
