You can merge several photos into a single picture on an iPhone without installing anything — the Shortcuts app does it. Whether that is the right choice depends on what you need: a quick side-by-side for a message, or a full-resolution grid you will keep.
Here are the four methods that actually work on iOS 17 and later, starting with the free built-in ones.
1. The Shortcuts app (free, no download)
iOS ships with a Combine Images action that merges photos into a grid, a horizontal strip or a vertical stack. You build the shortcut once and reuse it forever.
- Open Shortcuts and tap + to create a new one.
- Add the Select Photos action and turn on Select Multiple.
- Add Combine Images. Tap the layout to choose Grid, Horizontal or Vertical, and set the spacing if you want gaps.
- Add Save to Photo Album.
- Name it, then run it from the Shortcuts app, the Home Screen or the share sheet.
Good for: free, no watermark, keeps full resolution. Watch out: the layout is fixed — you cannot drag the borders, reframe a photo inside its cell, or preview the result before it saves. Getting the arrangement you pictured often means running it several times.
2. Notes or Freeform, then a screenshot
Paste the photos into a note, drag them next to each other, take a screenshot and crop. Freeform gives you a bigger canvas and snapping.
Good for: a rough side-by-side you are about to send in a chat, right now. Watch out: a screenshot captures at screen resolution. A 48 MP photo becomes roughly a 1 MP slice of a screenshot — fine on a phone, visibly soft when printed or zoomed, and the original EXIF date and location are gone.
3. Instagram, Canva and the big editors
Instagram has a built-in collage layout, and Canva, Picsart and PicCollage all make grids among their hundreds of other features.
Good for: when you also want stickers, text, filters and templates. Watch out: free tiers of these apps often add a watermark or an ad on export, and most have moved to subscriptions. If all you want is a grid, you are carrying a lot of app you will not use.
4. A dedicated collage app
A focused app trades breadth for speed: it opens straight into layouts and exports at full resolution.
How it works in Tilea
- In Photos, select the pictures you want.
- Tap Share, then Tilea.
- Layouts appear immediately — tap to switch, drag the borders to resize, pinch a photo to reframe it inside its cell.
- Save. The collage lands in your library at full resolution.
No watermark, no ads, no subscription, and it works offline — everything runs on the device. The collage keeps the original date, location and camera details, so it files itself in the right place in your timeline instead of jumping to today.
Get Tilea on the App Store →Which method should you use?
| Method | Full resolution | Watermark | Best for |
|---|---|---|---|
| Shortcuts | Yes | No | A repeatable layout you do not need to preview |
| Notes screenshot | No | No | A throwaway side-by-side in a chat |
| Big editors | Usually | Often on free tiers | Collage plus heavy decoration |
| Dedicated app | Yes | Depends on the app | Control over the layout, kept at full quality |
Common questions
Can I combine photos on iPhone without an app?
Yes — the Shortcuts method above uses only what is already on your phone. It is genuinely free and adds no watermark.
How do I put two photos side by side?
In Shortcuts, set Combine Images to Horizontal for side by side, or Vertical to stack them. In a collage app, pick a two-cell layout — that is also the fastest route for a before-and-after comparison.
Does combining photos reduce quality?
Only if the method does. Screenshots capture at screen resolution and lose a lot. Shortcuts and full-resolution apps keep the original pixels — the combined image is as sharp as the photos that went into it.
Why did my collage appear at the top of my library instead of with the originals?
Because most tools stamp the new file with today's date. If the app carries over the original photo's date and location — Tilea does — the collage sorts next to the moment it came from.
