Collage Maker

Choosing a collage layout

A good collage starts with the right layout for your photos. The layouts on offer depend on how many photos you add, from 2 to 12, and fall into three groups:

• Even grids such as 2 by 2 or 3 by 3 give every photo the same weight. They suit a series, like the steps of a recipe, outfits of the week or products in one shot each.
• One large photo with small ones puts a hero picture first and frames it with details. This is the classic choice for a trip, an event or a product page: the wide view large, the close ups small.
• Rows and columns of different counts, like 2 on top and 3 below, are useful when the number of photos does not make a neat grid, and they look less rigid than a grid.

Landscape photos sit best in wide frames and portrait photos in tall ones, but you can always choose what shows: every frame is filled completely, and you drag the photo inside it to pick the part that matters. Nothing is stretched or squeezed; the photo is scaled evenly until it covers the frame, and the rest is cut off at the edges.

Canvas sizes for posts, stories and prints

The four shape buttons set a canvas with a short side of 2,160 pixels, which is plenty for sharing and for a print of a few inches. Square suits a feed post, 4:5 a portrait post, 9:16 a phone screen or story, and 16:9 a widescreen display or slide. You can also type any width and height in pixels.

The list of post and story sizes uses only numbers the platforms publish themselves:

Sizes change from time to time, so check the source when an exact number matters. For more platforms and placements, see the social media image sizes overview.

Spacing, border, corners and background

Spacing is the gap between two photos, and the outer border is the frame around the whole collage. Both are set in pixels of the saved image and drawn in the background color. The tool computes the frames so that every gap is exactly as wide as you set, the frames fill the canvas to the last pixel, and frames that should be the same size differ by at most one pixel where the space does not divide evenly. Rows and columns line up across the whole collage, so there are no thin seams or crooked edges.

The corner radius rounds the corners of every photo. With no spacing, rounded corners leave small gaps where the background shows through, which can look nice with a dark or colored background. A transparent background only stays transparent in a PNG file; in a JPG it turns white, because JPG has no transparency.

Moving, zooming and swapping photos

Click or tap a photo to select it. Drag it to move the picture inside its frame, and use the Zoom slider or a two finger pinch to get closer. Center puts it back in the middle at the smallest zoom, where it just fills the frame. With the keyboard, focus a photo and use the arrow keys to move it and plus or minus to zoom.

To change the order, drag the round handle in the corner of a photo onto another one. On a phone, a tap on the handle followed by a tap on the other photo does the same. Replace swaps in a new picture at the same spot, and Remove takes a photo out; the layouts then adjust to the new count.

Phone cameras often store pictures sideways with an EXIF Orientation tag that says how to turn them, which browsers follow by default according to MDN. The tool applies the tag too, so every photo opens upright as your gallery shows it and you never have to fix the rotation first. If a photo still needs a turn, the rotate and flip tool handles it, and the image cropper trims a single picture to an exact shape.

Full resolution and file size

The preview on screen is a small copy, but the saved collage is drawn from your original photos at the full canvas size. When a photo has more pixels than its frame needs, it is scaled down smoothly; when it has fewer, it is enlarged and can look soft, so give the large frame of a layout your sharpest picture. JPG at quality 92 keeps photos looking like the originals at a fraction of the size of a PNG. To make the file smaller for email or a website, run it through the image compressor afterwards.

How to use the collage maker

1. 1Drop 2 to 12 photos on the box or choose them from your device or phone gallery. Paste works too.
2. 2Pick a layout and a canvas size, then set spacing, border, corner radius and background. Drag each photo to frame it, and drag the handles to swap photos.
3. 3Choose JPG or PNG and press Download collage. The file is saved at the size shown above the button.
