Merge PDF — FAQ

How do I merge PDF files?
Drop in two or more PDFs, drag them into the order you want, and click Merge — you get a single combined PDF, downloaded instantly.
Is it free and private?
Yes — completely free, no signup, and the merging happens in your browser, so your PDFs are never uploaded anywhere.
Is there a limit on how many PDFs I can combine?
No fixed limit — merge as many as you like. Very large files just take a little longer since everything is processed on your device.
Can I reorder the files before merging?
Yes — use the up/down arrows to arrange the PDFs, and they’ll be combined in exactly that order.
