How to Merge PDF on Mac Free (3 Easy Ways)
Mac users have multiple free options for merging PDF files. You can use the built-in Preview app, use PDFcraft in your browser, or use a quick Finder shortcut. Here are all three methods explained step by step.
Method 1 — PDFcraft (easiest, works on any Mac)
Open Safari or Chrome on your Mac
Go to getpdfcraft.com. No software installation needed — works in any browser.
Click Merge PDF
Select the Merge PDF tool from the homepage.
Add your PDF files
Click Select Files and choose all the PDFs you want to merge. Drag them into the correct order.
Click Merge and download
Click Merge PDFs and download the combined file. Done in seconds.
Method 2 — Mac Preview app (built-in, no download)
Open the first PDF in Preview
Double-click the first PDF file. It opens in Preview automatically.
Show the Thumbnail panel
Go to View → Thumbnails to show the page thumbnails panel on the left.
Drag the second PDF into the thumbnail panel
Open Finder, find the second PDF, and drag it into the thumbnail panel in Preview. Drop it where you want it to appear — before or after existing pages.
Repeat for all PDFs
Drag as many additional PDFs as you need into the thumbnail panel in the correct order.
Save the merged PDF
Go to File → Export as PDF and save the merged document. Important: use Export as PDF, not just Save, to avoid overwriting the original.
Method 3 — Quick Action in Finder (macOS Mojave and later)
Select multiple PDFs in Finder
Open Finder and select all the PDF files you want to merge by holding Command and clicking each one.
Right-click and select Quick Actions
Right-click the selected files and look for Quick Actions → Create PDF. This merges them into one PDF automatically.
Find the merged PDF
The merged PDF appears in the same folder as the original files, named after the first file.
Which method is best for Mac?
Use PDFcraft for simplicity
PDFcraft is the easiest — no software needed, works on any Mac, and lets you reorder files before merging.
Use Preview for occasional use
Preview is built into every Mac and works well for occasional merging without going online.
Use Quick Action for speed
The Finder Quick Action is fastest if you just need to quickly combine files without reordering.
💡 Pro tip
When merging PDFs in Preview, always use File → Export as PDF to save. Using regular Save can overwrite your original file.
