Creating photo collages with grid layouts

A photo collage combines multiple images into a single composition, typically arranged in a grid or strip layout. Collages tell visual stories, compare before-and-after states, showcase product variations, or simply combine related photos into one shareable image. They are widely used on social media, in portfolios, and for personal photo projects.

Grid layouts divide the canvas into equal cells arranged in rows and columns. The tool automatically calculates the optimal grid dimensions based on your image count — 4 images become a 2x2 grid, 9 images become 3x3, and so on. Each image is cover-fitted into its cell, meaning it fills the entire cell while maintaining aspect ratio (excess is cropped from edges).

Strip layouts arrange images in a single row (horizontal) or single column (vertical). These work well for panoramic sequences, step-by-step progressions, or timeline-style presentations. The cell size, gap between images, and background color are all configurable to match your design needs.

The gap setting adds consistent spacing between cells, creating a clean grid appearance. A white or colored gap acts as a visual separator that helps each image stand out individually while remaining part of the larger composition. Setting gap to zero creates a seamless mosaic where images touch edge-to-edge.

Common use cases

• Instagram carousel alternatives: Combine multiple photos into a single collage image when you want to share several related photos without creating a multi-slide carousel post.
• Before and after comparisons: Place before and after images side by side in a horizontal strip to clearly show transformations, renovations, makeovers, or editing results.
• Product variation displays: Showcase multiple color options, angles, or configurations of a product in a single grid image for e-commerce listings or social media ads.
• Event photo summaries: Combine the best moments from an event into a single shareable collage that captures the overall experience in one image.

Technical details

Layout modes

Grid (automatic rows and columns), horizontal strip (single row), and vertical strip (single column). Grid dimensions are calculated to be as square as possible for the given image count.

Cover fitting

Each image is scaled to completely fill its cell while maintaining aspect ratio. Excess content is cropped equally from opposite edges. This ensures no empty space within cells.

Gap and background

Configurable pixel gap between cells filled with the chosen background color. Gap of 0 creates edge-to-edge placement. Background color shows in gaps and any unfilled areas.

Output resolution

The collage canvas size is determined by cell size multiplied by grid dimensions plus gaps. Large cell sizes produce high-resolution output suitable for printing.
