Collage Maker

How to make a photo collage

1. Drop 2 to 9 photos on the drop zone, or click it to choose them. They appear under Your photos and fill the cells in order.
2. Choose the Number of photos, then a Layout: even grids, or mosaics with one or two large cells beside smaller ones. The small drawings show the arrangement of each layout.
3. Pick the Shape of the collage (1:1, 4:5, 3:4, 2:3, 9:16, 16:9, 3:2 or 4:3) and its Width in pixels, from 1080 to 4000. The exact output size is shown under the editor.
4. Arrange the photos: - drag a photo from Your photos onto a cell, or select a cell and click a photo to put it there (a photo already used swaps places with the one it replaces); - drag inside a cell to move its photo, and zoom with the mouse wheel, a pinch or the Zoom slider; - Empty this cell removes the photo from the Selected cell; Refill in order puts all photos back in their original order.
5. Adjust Spacing, Rounded corners and Background color.
6. Choose the Output format, JPG or PNG, and click Download collage.

The editor also works with the keyboard: pick a cell in the Selected cell list, focus the collage, move the photo with the arrow keys and zoom with + and −.

Grid or mosaic?

A grid gives every photo the same weight and suits series: a day’s highlights, a product range, before-and-after pairs or a group of portraits. A mosaic puts one picture forward and uses the others as supporting details, which reads well for stories, event recaps and real-estate listings: the large cell draws the eye first.

Each cell crops its photo to fill it, like a picture frame. Nothing is stretched: the photo is scaled uniformly, and panning decides which part shows. Zooming in gives a tighter crop; the photo can never be moved so far that an empty area appears in the cell.

Choosing the size and format

For printing, divide the width in pixels by the print width in inches to get the resolution: 3000 px over 6 inches gives 500 pixels per inch, well above the usual 300 ppi. Very large tall collages are scaled down slightly to stay within the canvas size every browser supports (about 16.7 million pixels).

JPG makes much smaller files and suits photos. PNG is lossless and larger; choose it when the collage has fine text or will be edited again.

Spacing and style

Spacing is measured in pixels of the final collage and is applied both between cells and around the edge, so all gaps are equal. Set it to 0 for a seamless mosaic. Rounded corners rounds every cell; combined with a white or pastel Background color, it gives a soft, modern look. A dark background makes colors pop.

Your photos never leave your device: they are read and assembled in your browser, and the collage file has no EXIF metadata.
