How to Combine Two Photos on iPhone

The Photos app on iPhone can crop, rotate, adjust and mark up a picture, and it cannot put two pictures into one.

That gap is why “how to combine two photos on iPhone” is such a common search, and why the results are full of collage apps that want five dollars a month and stamp a watermark on the free tier.

You do not need any of them. iOS already ships with everything required, in a place most people never open. Here is the honest version, including which route I actually use.

What your iPhone can already do, before you install anything

Three native options exist, and each suits a different job.

Shortcuts has a built-in action called Combine Images. It takes a set of photos and joins them horizontally, vertically, or in a grid, with a spacing value you control. This is the cleanest route and it produces a single flat image with no branding on it. It is buried inside an app most people opened once and closed.

Freeform is Apple’s own canvas app and it comes preinstalled. You drag two photos onto a board, arrange them however you like, and export the board. It is the right pick when you want overlap, captions, arrows, or anything that is not a plain side by side join.

Markup inside Photos lets you draw and add text on a single image, and it will not import a second photo onto the canvas. People try this first and get stuck, so I am saying it up front to save you the detour.

Route one: the Shortcuts action, which is the one I use

This takes about two minutes to build once and then lives in your share sheet forever.

1. Open the Shortcuts app and tap the plus button at the top right.
2. Search the action list for Combine Images and add it.
3. Tap the blue Input word in that action and set it to Shortcut Input, so it picks up whatever you share into it.
4. On the Combine Images action, choose Horizontally, Vertically or In a Grid, and set Spacing to something like 10 if you want a small gap between the two photos.
5. Add a second action, Save to Photo Album, underneath it.
6. Open the shortcut’s settings, the info icon, and turn on Show in Share Sheet. Set the accepted types to Images only.
7. Name it something obvious like Join Photos and tap Done.

To use it, open Photos, tap Select, pick your two images, tap the share button, scroll down, and tap Join Photos. The combined image lands in your camera roll a second later.

The order matters. The images join in the order Photos hands them over, which follows their date order rather than the order you tapped them, so if the result is backwards, that is why.

If the Shortcuts editor looks intimidating, ignore the sidebar full of automation options. You are using two actions out of several hundred, and once the shortcut is saved you never open the editor again.

Route two: Freeform, for anything more designed

Combine Images gives you a rigid layout. When you want one photo overlapping another, a caption between them, or three photos in an uneven arrangement, use Freeform instead.

1. Open Freeform and tap the pencil-and-square icon to start a new board.
2. Tap the photo icon in the toolbar, choose Photos, and insert your first image. Repeat for the second.
3. Drag and pinch each one into place. Pinch outwards on the canvas first if you need more room.
4. Tap the three dots at the top right, choose Export as PDF, or take a screenshot of the arranged area if you want an image.

The PDF export is the sharper result, since a screenshot is limited to your screen resolution. If you go the PDF route and then need an image back out of it, converting a PDF to images on iPhone closes that loop.

Route three: when you actually wanted a PDF all along

A surprising share of “combine two photos” searches are really about paperwork. Two sides of an ID card, a two page form photographed on a table, a receipt and its back. In that case do not make a collage.

Make one PDF with two pages, which is what the other side expects to receive. iOS does this natively through the Print sheet, and I wrote out the full sequence in turning multiple photos into one PDF on iPhone.

Where Grabio fits, and where it does not

I will be straight about this. Grabio does not have a combine option. The joining is done by Apple’s own Combine Images action, or by Freeform, and I am not going to claim credit for either.

What Grabio handles is everything that happens to that combined image afterwards, and that is usually where people get stuck.

A joined image is roughly the size of both originals added together, so it is often too heavy for an upload form or an email. Grabio’s on-device tools cover compressing it, resizing it to exact pixel dimensions, cropping it square for a social post, stripping the location data out of it, or turning it straight into a PDF.

All of that runs on your phone through Apple’s own image actions, with nothing uploaded anywhere.

The two I reach for most after a join are reducing a photo’s file size and resizing a photo to exact dimensions when a form demands a specific pixel size.

Two problems that catch people out

Different sizes give you an ugly join. Combine Images matches the images along the joining edge, so a portrait photo next to a landscape one leaves the shorter side padded or scaled oddly. Crop both to the same aspect ratio first. Cropping to a square before joining fixes this in most cases.

The output has the location of both originals. A combined image can inherit metadata you did not think about. If it is going to a marketplace listing or a public post, strip the location first. That matters more than people assume, and I covered why in removing location data from a photo.

Set it up once

Build the Combine Images shortcut this evening and it is there permanently. Then Get the Shortcut for the compress, resize, crop and PDF steps that come after, so the whole sequence stays on your phone with nothing uploaded.

FAQ

Can I combine two photos in the Photos app itself?

No. The Photos editor works on one image at a time, and Markup will not let you import a second picture onto the canvas. You need the Shortcuts app, Freeform, or a third party app. Shortcuts is free, already installed, and adds no watermark.

Will combining two photos lose quality?

The Combine Images action keeps both images at their original pixel dimensions and places them next to each other, so there is no downscaling. The saved result is a JPEG, so it carries JPEG compression, though at normal quality that is invisible on screen.

How do I control which photo goes on the left?

The share sheet passes images in the order Photos holds them, which is by date rather than the order you tapped. If the result is reversed, the simplest fix is to duplicate one photo so its date changes, or to use Freeform where you place each image by hand.

Can I combine more than two photos this way?

Yes. Select as many as you like and the same shortcut handles them. Use the In a Grid option once you go past three, since a horizontal join of six photos produces a very wide, very thin image.

Does Grabio combine photos for me?

No, and I would rather say so. Grabio has no combine tool. Apple’s Combine Images action does the joining. Grabio covers what comes next, which is compressing, resizing, cropping, stripping location data, or converting the result to PDF, all on-device.

Why is my combined photo so large?

Because it contains both originals at full resolution, so the file is roughly the sum of the two. Modern iPhone photos are big to begin with. Run the result through a compression step before emailing or uploading it and the size usually drops sharply with no visible difference.
