Your options for merging PDFs on Mac

Mac users have three main ways to merge PDFs:

  • macOS Preview — built-in and free, but requires a multi-step drag-and-drop process between windows
  • Adobe Acrobat — straightforward, but $19.99–29.99/month
  • Browser-based tools — free, no install, simpler interface than Preview

Method 1: Merge PDFs using PrivaPDF (recommended)

Works in Safari, Chrome, and Firefox on any Mac — Intel or Apple Silicon.

Go to privapdf.net/tools and click the Merge tab. No account or download needed.

2
Add your PDFs

Drag all the PDF files you want to combine from Finder onto the page. Or click to select them. They load directly in your browser — nothing is uploaded.

3
Reorder if needed

Drag the file thumbnails to arrange them in the correct order — the order they appear is the order they'll be merged.

4
Merge and download

Click Merge PDFs. The combined PDF downloads straight to your Mac's Downloads folder.

Method 2: Merge PDFs using macOS Preview

Preview is free and works without an internet connection, but the process is less intuitive:

1
Open the first PDF in Preview

Double-click the first PDF to open it in Preview.

2
Show the Thumbnails sidebar

Go to View → Thumbnails to show the sidebar.

3
Drag the second PDF into the sidebar

Drag the second PDF file from Finder directly into the Thumbnails sidebar. Drop it where you want it — after the last page of the first PDF, or between pages.

4
Export as PDF

Go to File → Export as PDF to save the merged document. Don't use Save — that will modify the original file.

Preview tip: Always use Export as PDF rather than Save when merging. Saving overwrites the original file, which may not be what you want.

Frequently asked questions

Does PrivaPDF work in Safari on Mac?

Yes. PrivaPDF is fully compatible with Safari 16+ on macOS Ventura, Sonoma, and later.

Can I merge more than two PDFs at once?

Yes. PrivaPDF supports merging multiple PDFs in one operation — just add all the files at once and reorder them as needed.

Does it work on Apple Silicon Macs (M1/M2/M3)?

Yes. WebAssembly is fully supported on Apple Silicon and typically runs faster than on Intel Macs.

Will the merged PDF preserve fonts and formatting?

Yes. Merging PDFs combines the page content directly — fonts, images, and formatting are preserved exactly as they were in the original documents.
