Files stay on your device. Most tools (merge, split, sign, edit) run entirely in your browser; nothing is uploaded.

How to combine PDF files into one

Sending five separate PDFs is annoying for whoever receives them. Combining them into one ordered document is cleaner, and it takes a few seconds.

Open Merge PDF

Step by step

  1. 1Open the Merge PDF tool and drop all your PDFs in.
  2. 2Drag them into the order you want them to appear.
  3. 3Click Merge and download the single combined file.

Getting the order right

The merged file follows the order you arrange the files in, top to bottom. Drag them around before merging, and add more at any time.

If you only need some pages from a file, extract those pages first, then merge the results.

Does merging upload my files?

No. This tool runs entirely in your browser, so the PDFs are combined on your own device and never sent anywhere. That matters when you're merging contracts, statements, or anything private.

FAQ

Is there a limit on how many PDFs I can merge?
No fixed limit. Add as many as you need; very large combinations just take a moment longer to process on your device.
Can I merge files of different page sizes?
Yes. Pages keep their original size in the combined document.
Is it free?
Yes, completely free, with no account, and nothing is uploaded.
