Photo Collage Maker

Choosing a layout

Layouts are offered for the number of photos you add, so every cell is filled. Equal grids — side by side, 2 × 2, 3 × 2, 3 × 3 — treat every photo as equally important and suit a set of similar pictures: a product range, a before-and-after, a run of holiday shots.

Mixed layouts give one photo more room. 1 + 2 puts a large picture on the left with two stacked on the right; 1 + 3 puts a wide picture on top of three; 1 + 5 places one large photo across four cells of a 3 × 3 grid with five around it. Use them when one image is the story and the others support it — the couple and then the guests, the finished dish and then the steps.

Row-based layouts such as 2 + 3 or 3 + 2 + 3 mix wide and narrow cells and look less rigid than a strict grid. They are a good choice for odd numbers of photos, which never divide into a tidy grid.

Sizes for where it is going

1080 × 1080 is a square post. 1080 × 1350 is the 4:5 portrait size that takes up the most room in a phone feed, which is why many people prefer it for posts. 1080 × 1920 is the 9:16 size for stories, reels covers and status updates. 1920 × 1080 is 16:9 landscape, for slides, video thumbnails and desktop wallpapers.

A4 at 300 dpi is 2480 × 3508 pixels portrait, or the same turned landscape, for printing at home or at a print shop. 300 pixels per inch is the usual target for prints viewed at arm's length. Bear in mind what that means per cell: in a 3 × 3 grid on A4, each photo is around 780 pixels wide, so any phone photo is ample, but a picture saved from a messaging app at 640 pixels will be slightly enlarged.

The tool warns you when a photo is being shown at much more than its own resolution, because that is the one way a collage can disappoint: it looks fine on screen and soft in print.

Framing each photo inside its cell

Every photo fills its cell completely, scaled so it covers the cell and cropped where its shape differs — a landscape photo in a tall cell loses its sides. That avoids empty bars, but means the default crop is the centre, which is not always where the subject is.

Click a cell to select it and drag inside it to slide the photo until the right part is in view; the arrow keys do the same. Zoom crops in further, up to four times, for when the subject is small in the frame. Re-centre undoes both. The crop is stored relative to the photo, so what you frame in the preview is exactly what the full-resolution collage contains.

To change which photo is in which cell, select it and use Swap with previous or Swap with next. The photo strip above shows the current order with cell numbers.

Spacing, corners and background

Spacing sets the gap between photos and around the outside edge, and the two are always the same width — a detail that cheaper tools get wrong, leaving a thin outer margin and thick inner gutters. Spacing and corner radius are defined on a 1080-pixel scale and grow with the canvas, so 16 pixels of spacing looks the same proportion on a square post and on an A4 page.

No spacing gives a seamless mosaic; 8–20 gives a clean gallery look; wider gaps with rounded corners give a softer, scrapbook feel. The background colour shows through the gaps — white is classic, black is dramatic, and a colour picked from the photos themselves ties the set together.

Saving, and what is not included

JPEG is the right format for a collage of photographs and keeps the file small enough for any messaging app. PNG is lossless and much larger, worth it only when the collage contains screenshots or graphics with fine text. Each photo is read again at full resolution when you save, so the preview's smaller copies never limit the quality of the result.

There is no watermark and no account. The photos — often family pictures, which is exactly the kind of image you might prefer not to upload — are combined in your browser and never sent anywhere.

This is a layout tool. It does not add text, stickers, frames or filters; to caption a collage, save it and open it in the add-text tool, and to adjust colour, run the photos through the photo editor first. The maximum is nine photos per collage.
