How to make a photo collage on an iPhone

The free way with nothing to install

The surprising part of this question is that Apple's Photos app has never had a collage feature, and none of the recent redesigns added one. It builds memory movies, which are slideshow videos, not a single flat image.

What the iPhone does have is Shortcuts, which is preinstalled, and a Combine Images action that stitches selected photos into a grid, a horizontal strip or a vertical stack with adjustable spacing. Apple's Shortcuts gallery includes a ready-made shortcut built on it, so you can add that rather than building your own: open Shortcuts, go to the Gallery tab, search for the photo grid shortcut and add it. Run it, pick your photos, and save the result to your camera roll.

To build one yourself, the sequence is three actions: Select Photos with Select Multiple turned on, then Combine Images set to Grid with your chosen spacing, then Save to Photo Album. It takes about two minutes and you keep it forever.

What this route gives you is a clean, evenly spaced grid at full resolution, free, with nothing installed and no watermark. What it does not give you is templates, text, borders, rounded corners or any control over which photo goes where beyond the order you tap them in. For a straightforward grid, that is usually all that was needed.

Four routes compared

Instagram's standalone Layout app was discontinued in 2024, which is why old instructions pointing at it no longer work. The layout feature survives inside Instagram Stories, and several unrelated apps now use the name, so check the developer before installing anything.

Layout choices that make it look designed

Five decisions separate a collage that looks made from one that looks generated.

Fewer photos, larger. Three or four images at a readable size beats nine thumbnails. On a phone screen, a collage of nine photos gives each one roughly the area of a postage stamp, and nobody looks at any of them.

Equal gutters, or none at all. Pick a spacing and use it everywhere, including the outer margin. Mixed spacing is the flaw the eye catches first, even when the viewer could not name it.

Crop to the slot, never stretch. If a portrait photo is going into a landscape space, crop it deliberately and decide what to lose. Letting the layout squash it is instantly visible on faces.

One image should dominate. A grid of identical squares has no entry point. Make one photo larger and the eye knows where to start, which is most of what composition means in a layout.

Treat the whole thing as one image. Same white balance, same contrast, same treatment across every photo. Four images with four different colour casts sitting in one frame is far more jarring than the same four scrolled past separately. Our guide on making your photos look consistent covers how.

Collages for Instagram specifically

Three practical notes if the collage is going to Instagram.

Match the shape before you export. A 4:5 portrait crop takes up the most screen space in the feed, square works for a grid-heavy layout, and a story collage should be 9:16. Building a collage at the wrong shape and cropping afterwards cuts images in half. The Instagram photo sizes guide has the numbers.

Export larger than you think, but not enormous. Instagram re-encodes everything on upload, and a collage suffers more than a single photo because it contains many small details and hard edges between images. Export at the platform's display size rather than at the maximum your app allows.

Stories layout mode is there when you need it quickly. Instagram's own grid lives inside the Stories camera, takes seconds, and is fine for a casual grid. It is not a route to a saved file, so if you want the collage for anything else, build it elsewhere.

Also worth knowing: a heavily grained or noisy photo inside a collage compresses badly, so if you have applied a film look with visible grain, ease it back before assembling.

When a carousel beats a collage

This is the advice most collage pages will not give you. On Instagram, a carousel is usually the better format, and it is worth being honest about why.

A carousel shows each photo at full screen size, so the detail survives. A collage shrinks every photo to a fraction of the frame, on a device people are holding at arm's length. If the photos are good, a collage is actively hiding them.

A carousel also asks for a swipe, which is a small interaction, and sets of photos that reward swiping tend to be seen by more people than a single static image. Our guide to picking photos for a photo dump is about building exactly that kind of set.

Collages genuinely win in four situations: when the comparison is the point, as in a before and after; when the images are individually weak but collectively meaningful, like tickets and receipts from a trip; when you need one image for a printed thing, a card or a gift; and when the grid itself is the aesthetic, as in a scrapbook page.

If none of those apply, post the photos separately and let them be seen.

What makes a collage look dated

Collage styles age faster than almost any other kind of photo edit, and four things date one immediately.

• Heavy drop shadows and thick white borders. The default look of collage apps from about fifteen years ago, still the default in several of them.
• Rounded corners on every image plus a patterned background. Two decorative decisions fighting each other. Pick at most one.
• Decorative fonts and stickers. Script fonts, sparkles, hearts and washi tape graphics all read as a template. If you want a scrapbook look, photograph real paper and tape instead, which looks better and is free.
• A different filter on each photo. The fastest way to make a collage look like a folder rather than a picture.

What ages well is unglamorous: equal spacing, a single background colour taken from one of the photos, consistent colour treatment, and one image larger than the rest. That will look fine in ten years, which is more than can be said for most of what a collage app suggests first.
