How to Merge PDF on Mac (Free, Better Than Preview)
Quick answer: Open DocMint Merge PDF in Safari on your Mac. Upload your PDFs, arrange them, and merge. Faster and more reliable than Mac Preview, completely free.
Mac Preview vs DocMint for Merging PDFs
Mac Preview can merge PDFs, but it's not the most intuitive tool for the job. The process involves dragging thumbnails between windows, and it's easy to accidentally reorder pages or create a corrupted file. DocMint gives you a cleaner, more reliable experience.

Method 1: DocMint in Safari (Recommended)
DocMint is the easiest way to merge PDFs on Mac. It works in Safari, Chrome, Firefox, and Edge — no installation needed.
Step 1: Open Safari
Open Safari on your Mac. DocMint also works in Chrome, Firefox, and Edge on macOS.
Step 2: Go to DocMint Merge PDF
Navigate to docmint.online/merge-pdf. The tool loads fully in your browser.
Step 3: Upload Your PDFs
Click Upload Files and select your PDFs from Finder. You can select multiple files at once using Cmd+Click. Your files are loaded into your browser's memory — nothing is uploaded to any server.
Step 4: Arrange the Order
Drag and drop the files to arrange them in the order you want. The first file becomes the first section of the merged PDF. This is much cleaner than Preview's thumbnail drag interface.
Step 5: Merge and Download
Click Merge PDFs. When complete, click Download. Safari saves the merged PDF to your Downloads folder.
Method 2: Mac Preview (Built-in Alternative)
If you prefer to use Preview, here's the correct process:
- Open the first PDF in Preview
- Go to View → Thumbnails to show the sidebar
- Open the second PDF in a separate Preview window
- In the second window, select all thumbnails (Cmd+A)
- Drag the thumbnails from the second window into the sidebar of the first window
- Position them where you want them to appear
- Go to File → Export as PDF to save the merged file
Preview warning:
Using File → Save (instead of Export as PDF) in Preview will overwrite the original file. Always use Export as PDF to create a new merged file and preserve your originals.
Method 3: Automator on Mac
For power users who merge PDFs regularly, macOS Automator can create a workflow:
- Open Automator (in Applications)
- Create a new Quick Action
- Add the Combine PDF Pages action
- Save the workflow
- Right-click multiple PDFs in Finder → Quick Actions → your workflow
This is powerful but requires setup time. DocMint is faster for occasional use.
After Merging on Mac
- Compress the merged PDF to reduce file size for email
- Reorganize pages if you need to reorder after merging
- Password protect the merged document
- Open in Preview for annotation if needed
