Merge PDFs Online Free — No Watermark

Combine multiple PDFs into a single document. Reorder before merging, drop in as many files as you need, then download the result — all in your browser, no upload.

How it works

  1. Drop your PDFs. Add as many PDFs as you want. Drag to reorder them once they're staged.
  2. Confirm the order. The first file's pages come first, then the second, and so on. Drag any tile to slide it earlier or later in the merged output.
  3. Download your merged PDF. Hit Merge. GhostPDF combines the PDFs locally and gives you a single file to download.

Frequently asked questions

How many PDFs can I merge?

There's no hard cap on count. The practical limit is your machine's memory — your browser holds every PDF while merging, so combined sizes over ~200MB may slow down on weak machines.

Will the page order be preserved?

Yes. Each input PDF's pages are appended in their original order, in the order you arranged the files.

Will the merged PDF have a watermark?

No. GhostPDF never adds a watermark, ad page, or branding to your file. The output is identical to a PDF you'd produce with desktop software.

Does the order I drop matter?

Drop order sets the initial sequence, but you can drag any file tile after to reorder. The final order is exactly what's on screen when you click Merge.

Do you keep a copy of my files?

No. We literally cannot — there's no upload step. Everything happens in your browser tab and is gone the moment you close it.

Is it free for unlimited merges?

Yes. No signup, no document caps, no watermark. Merge as many PDFs as you need, as often as you need.
