How to make a photo collage on a Mac: Shortcuts, Freeform, Keynote, and online
Photos for Mac edits one picture at a time, and Preview cannot enlarge a canvas to fit two, so the usual copy-and-paste advice ends in a crop. Three apps already on your Mac can do the job, and Safari can do it better. Here is each one, with what it cannot do.
1. Four ways at a glance
| Method | Already on the Mac | Photos | Layouts | Best for |
|---|---|---|---|---|
| Shortcuts (Combine Images) | Yes | Any number | Row or column | Two or three photos in a strip, full resolution |
| Freeform | Yes | Any number | Free placement | A scrapbook look, a mood board |
| Keynote or Pages | Yes | Any number | Manual, with alignment guides | A tidy grid or a poster |
| Safari, StudioCollage | Needs nothing | 2 to 12 in a grid, more on poster layouts | Grids, magazine, mosaic, shapes, auto; sizes and text | Posts, stories, prints, anything you will share |
2. 1. Shortcuts: a strip at full resolution
The Shortcuts app on macOS has the same Combine Images action as on the iPhone, and on the Mac it can take files straight from Finder.
- Open Shortcuts, click the plus button.
- Add Get File (or make the shortcut accept images as input from the Quick Actions menu), then Combine Images: Horizontally for side by side, Vertically for stacked, with an optional spacing.
- Add Save File, run it, choose the photos.
Good: original pixels kept, no app, thirty seconds once built, and you can put it in the Finder right-click menu as a Quick Action. Not good: a strip, not a grid; photos keep their own sizes; no text or border. The details are in two photos side by side.
Let Auto lay them out, then fix what you want.
Free, no watermark, and your photos stay on your device.
Open StudioCollage3. 2. Freeform: arrange by hand
Freeform is the whiteboard that came with macOS Ventura. Drag photos onto a board, resize, rotate, overlap, add text and shapes.
- Open Freeform, create a board, drag photos in from Finder or Photos.
- Arrange them with the guides that appear; add text boxes for captions.
- To get an image out: File, Export as PDF for a sharp file (good for printing), or select the area and take a screenshot (Shift-Command-4) for a quick share.
Good: freedom, fast for a mood board. Not good: no grid, no equal cells, no social sizes, and the export is a PDF or a screenshot rather than a clean PNG at 1080 pixels.
4. 3. Keynote or Pages: a page exported as an image
Keynote has the best alignment guides of the three, and exports a slide as a PNG.
- Open Keynote, pick a blank theme. Set the canvas: Document, Slide Size, Custom Slide Size. Use 2400 x 3000 points for an 8 x 10 print or 1080 x 1350 for an Instagram post (Keynote exports one pixel per point by default).
- Drag the photos onto the slide. Resize with the corner handles (proportions kept), align with the yellow guides, or select several and use Arrange, Align and Distribute.
- To crop a photo to a cell: double-click it to open the mask, drag the photo inside, click Done.
- File, Export To, Images, PNG.
Good: clean result, any size. Not good: every cell is manual, and it is a presentation file rather than a collage project. Fine for one poster.
5. 4. Safari: a real collage maker, nothing to download
Open a collage maker in Safari and the Mac becomes the best place to make a collage: a large screen, a trackpad, and every layout and size the built-in apps lack. StudioCollage runs entirely in the browser: the photos are read from your Mac and never uploaded, there is no account, and the export has no watermark.
- Open StudioCollage. The editor is the first screen; add it to the Dock from the Safari File menu if you want an icon, but it is not required.
- Choose the destination: Instagram post or story, Facebook cover, 8 x 10 or A4 print, a wallpaper for the Mac itself, or a custom size.
- Drag the photos from Finder or from the Photos app onto the page. Press Auto for several layouts that fit the count and keep faces whole, or pick a grid, a magazine page, a mosaic or a shape.
- Reframe a cell with a drag or the trackpad, set gaps and borders, take a background color from the photos, add a title.
- Download as PNG or JPG at the export size. The file lands in Downloads.
A 2x2 grid and a magazine page, made in Safari. Equal cells, clean gaps, export at the size you chose.
The project is saved in the browser on the Mac. The same page opens on your iPhone or iPad, so a collage started at the desk can be posted from the phone.
6. Which one today
- Two photos in a row: Shortcuts.
- A mood board or a scrapbook look: Freeform.
- One poster with careful alignment: Keynote.
- A post, a story, a print, a grid, text, more than four photos: Safari and StudioCollage.
For a print, export at the print size and follow the print guide. For the number of photos per format, how many photos to put in a collage; for every pixel size, photo collage sizes. On a PC, the equivalents are in the Windows 11 guide.
Frequently asked questions
Does the Mac have a built-in collage maker?
Not as such. Photos for Mac has no collage tool and Preview cannot combine two images. The built-in options are Shortcuts (Combine Images action), Freeform (a free board) and Keynote or Pages (place pictures, export the page as an image).
Can Preview put two photos side by side?
No. Preview can paste one image into another but cannot enlarge the canvas, so the pasted photo is clipped. Use the Shortcuts app instead: its Combine Images action joins any number of files in a row or a column at full resolution.
How do I make a collage in Keynote?
Set the slide size (Document, Slide Size, Custom), drag the photos onto the slide, resize and align them with the yellow guides, then File, Export To, Images, PNG. Keynote exports at the slide resolution, so make the slide large for a print.
What is the best free collage maker for Mac without download?
A browser one. StudioCollage runs in Safari or Chrome with no install and no account, offers grids, magazine and mosaic layouts, shapes and an auto mode, exports at social or print sizes without watermark, and never uploads your photos.
Can I use the same collage on my iPhone?
Yes. The browser editor is the same page on the iPhone, and a project saved in the browser on one device can be rebuilt on the other from the same photos. Files exported on the Mac land in Downloads and sync through iCloud Drive or AirDrop.
