Comprehensive Guide & Technical Mechanics

About Image Collage Maker — Free Online Tool

Image Collage Maker lays two to nine pictures out on one canvas — as a grid with the column count you choose, or as a single row or a single column.

Cells are square, at a size you set between 100 and 3000 pixels, and each picture is scaled to cover its cell and then centre-cropped to fit, so nothing is ever stretched out of shape. The consequence is that a tall portrait loses its top and bottom to a square cell. The gap between cells and the border around the outside are the same value, filled with a background colour you pick, and if your column count leaves cells empty the result says how many so you can tighten the grid.

Each picture is decoded and composited in your browser and none of them is uploaded.

Putting before-and-after shots side by side, building a contact sheet from a shoot, assembling screenshots into one image for a post, and making a simple photo grid to print.
