Merge PDF files

Merge PDFs without giving up your privacy

Almost every PDF-merging service uploads your documents to its servers, processes them there and sends the result back. Here it is the opposite: the merge is done with the pdf-lib library inside your own browser, so contracts, payslips or invoices never leave your device.

Documents are combined in the order they appear in the list, keeping the size and orientation of each original page. Password-protected PDFs can't be processed; unlock them first with the password in your usual reader.
