About this tool
Create beautiful photo collages from your images with customizable layouts and spacings.
Image Collage Maker arranges the photos you drop in on a fixed 1200 x 1200 pixel canvas using one of four layouts — auto grid, 2x2, single row or single column — and exports the result as a full-quality PNG. Each photo is centre-cropped to fill its cell rather than squashed, so aspect ratios stay correct whatever mix of portrait and landscape shots you add. The gutter between cells is a slider from 0 to 50 pixels, and the preview redraws as you move it.

Each image is scaled to cover its cell and centre-cropped, so a portrait shot next to a landscape one never comes out stretched.
Grid mode takes the square root of your photo count to pick columns, so five photos or twelve photos both land in a sensible arrangement.
Anywhere from 0 px for an edge-to-edge mosaic to 50 px for a framed look, with the canvas redrawing as you drag.
1200 x 1200 pixels, saved as a PNG at full quality. That square size suits most social feeds and prints acceptably at small sizes, and cell dimensions are derived from it after the spacing gutters are subtracted.
There is no fixed cap on uploads, but the chosen layout decides how many are drawn: 2x2 shows the first four, horizontal and vertical show all of them in a single row or column, and auto grid uses a roughly square arrangement based on how many you added. Anything beyond the layout's cell count is left out of the render.
No. Files are read with the browser's FileReader and drawn to a canvas in the page, and the download comes from that canvas, so the images never leave your device.
Because each cell is filled by scaling the image to cover it and cropping the overflow from the centre — the alternative would be letterboxing or distortion. Cropping is most noticeable when a tall portrait photo lands in a wide cell, so try the vertical layout or a different photo order if an important edge is being lost.
