How to combine PDF files on Mac — your Mac already has everything you need, no Adobe, no downloads, no subscriptions. Here are 4 free methods that work on every Mac, including the latest macOS Sequoia and Sonoma.
Preview is Apple's free PDF viewer that comes pre-installed on every Mac. Most people use it to view PDFs, but it's also a surprisingly capable PDF editor — including merging multiple files into one.
Best for: Combining 2–5 PDFs quickly. No internet required.
Double-click any PDF — it opens in Preview by default on Mac. If it opens in another app, right-click the file and choose Open With > Preview.
Go to View > Thumbnails in the menu bar, or press ⌥ Option + ⌘ Cmd + 2. You'll see a panel on the left showing each page as a small preview.
Open a Finder window alongside Preview. Drag your additional PDF files directly into the thumbnail sidebar. Drop them above or below an existing page to control the order.
Drag any thumbnail up or down within the sidebar to rearrange pages. You can also delete pages by selecting a thumbnail and pressing Delete.
Go to File > Export as PDF. Choose a filename and save location, then click Save. Your combined PDF is ready.
Preview gets awkward with large batches. RapidTools handles unlimited files in one drag-and-drop — still no software needed.
🔗 Merge PDFs Free — No Download →If you have more than 5 PDFs to merge, or files scattered across different folders, a browser-based tool is faster and easier than Preview. RapidTools works entirely inside Safari or Chrome on your Mac — your files never get uploaded to any server.
Best for: Large batches, files from multiple folders, or when you want a cleaner drag-and-drop experience. Works on any Mac without installing a thing.
Open rapidtools.online/merge-pdf in Safari, Chrome, or Firefox on your Mac. No login, no account needed.
Drag as many PDF files as you want directly onto the upload zone. Or click to browse your Mac's files. You can add files from multiple folders at once.
Use the ↑ and ↓ buttons on each file to arrange them in the right order before merging.
The merged file downloads directly to your Mac's Downloads folder. No watermarks, no sign-up, no limits.
If you're running macOS Mojave (10.14) or later — which includes Big Sur, Monterey, Ventura, Sonoma, and Sequoia — you have a hidden merge feature built right into Finder.
Best for: Quick merges where file order doesn't matter much. No apps needed at all.
Hold ⌘ Cmd and click each PDF you want to combine. The order you select them determines the merge order.
Right-click (or Control-click) on your selected files. Hover over Quick Actions in the context menu.
Select Create PDF from the Quick Actions submenu. macOS will instantly create a new merged PDF in the same folder, named after the first file.
Automator is a workflow automation tool built into macOS. You can create a reusable workflow that merges PDFs with a single click — ideal if you regularly combine PDFs as part of a recurring task.
Best for: People who merge PDFs frequently and want a one-click solution they can reuse.
Press ⌘ Cmd + Space, type Automator, and press Return. Choose New Document and select Quick Action as the workflow type.
At the top of the workflow, set Workflow receives current to PDF files in Finder.
In the left panel, search for Combine PDF Pages and drag it into your workflow. Choose Appending Pages.
Add Move Finder Items after the previous step and set the destination to your preferred folder (e.g. Desktop or Downloads).
Press ⌘ Cmd + S to save with a name like "Merge PDFs". Now select PDFs in Finder, right-click, and find your workflow under Quick Actions.
Here's a quick comparison of all four methods to help you pick the right one:
| Method | Best for | File order control | Large batches | Setup needed |
|---|---|---|---|---|
| Preview | 2–5 files, offline | ✓ Full | ✗ Slow | ✓ None |
| RapidTools (browser) | Any batch size | ✓ Full | ✓ Fast | ✓ None |
| Finder Quick Action | Quick 2-file merges | ⚠ Limited | ✗ No | ✓ None |
| Automator | Recurring workflows | ⚠ Limited | ✓ Yes | ✗ One-time setup |
No software, no account, no watermarks. Works in your browser on any Mac — files never leave your device.
