How to use Merge PDF
- Drop or select two or more PDF files.
- They are combined in the order shown — remove any you don’t want.
- Click “Merge PDFs” to download the single combined file.
Is it private?
Yes. Merge PDF runs 100% inside your web browser. Your files are never uploaded to a server, so even we can’t see them. That makes it a safe choice for sensitive spreadsheets, contracts, and personal documents.
Frequently asked questions
Is there a limit on how many PDFs I can merge?
No. Because the work happens on your own computer, you can combine as many files as your device can handle.
Are my files uploaded anywhere?
No. Merging runs entirely in your browser — your PDFs never leave your device.
