How to Merge PDFs on Mac — Free, No Adobe, No Preview

Mac comes with Preview — but combining PDFs in Preview is less intuitive than Apple suggests. For a faster, safer way to merge PDFs on Mac: open PDFWix in Chrome or Safari, upload your files, drag to reorder, and download the merged result. No install, no Adobe subscription, no file modification risk.

How to Merge PDFs on Mac — Free, No Adobe, No Preview

Merge PDFs on Mac free in Chrome or Safari — no Adobe, no Preview tricks. Drag, reorder and download in seconds. No install, no signup, no watermark today.

Bonus tip: merging Preview-rotated pages

If your source PDFs include pages you previously rotated in Preview, double-check the rotation actually saved to the file (⌘S) before merging — Preview sometimes shows the rotated orientation on screen even when the underlying page is still in its original orientation. PDFWix merges what's in the file, not what's on screen. For mixed-orientation documents (landscape charts inside a portrait report), the merge preserves each page's saved orientation correctly, so a single merged PDF can contain both portrait and landscape pages without re-rotating anything.

How it works

  1. Open Merge PDF — Go to pdfwix.com/merge-pdf in Chrome or Safari on your Mac. No account needed.
  2. Upload your PDFs — Drag PDFs from Finder onto the upload area or click Select files.
  3. Reorder pages — Drag thumbnails to set the final order. Add more files at any time.
  4. Merge — Click Merge PDF. Your browser combines the files locally using WebAssembly.
  5. Download — Save the merged PDF to your Mac's Downloads folder.
