Combine PDF – frequently asked questions
Is this PDF merger free?
Yes. Combining PDFs on Sehnna is free, with no signup, no watermark and no limit on the number of files.
Can I change the order of the PDFs?
Yes. Use the up and down arrows next to each file (or drag and drop on desktop). The files are combined from top to bottom.
Are my PDFs uploaded?
No. The PDFs are merged directly in your browser. Your files stay on your device and are never uploaded to a server.
Will the quality of my PDFs change?
No. Pages are copied exactly as they are, so text stays selectable and images keep their original quality.
Can I combine password-protected PDFs?
Not yet. Please remove the password from a protected PDF first, then combine it.
