How to Merge PDFs on Mac — 3 Free Methods
macOS has a built-in PDF merger in Preview. Here are 3 free ways to combine PDFs on your Mac.
Method 1: Merge PDFs with macOS Preview (Built-in)
- Open the first PDF in Preview
- Go to View > Thumbnails to show the sidebar
- Drag the second PDF file from Finder into the thumbnail sidebar, positioning it where you want
- Repeat for more files
- Go to File > Export as PDF and save
This is the most private method — everything stays on your Mac, no internet needed.
Method 2: Use DocMind in Your Browser
DocMind Merge PDF also runs entirely on your device. Open Safari or Chrome, go to the tool, upload your files and merge. Easier than Preview for many files.
Method 3: Automator (For Regular Tasks)
If you regularly merge PDFs, Automator (built into macOS) can create a workflow or right-click service: New Document > Workflow > Add "Combine PDF Pages" action. Save as a Quick Action for instant access from Finder.
