About This Operation
What to Expect
The PDF binder keeps each source document's pages in the exact order shown in the queue. Reorder files with the drag handle or keyboard controls before combining.
qpdf combines the validated PDFs without normalizing every page, so mixed page sizes and portrait or landscape orientations are retained.
Supported input
Accepts PDF sources only. Password-protected, encrypted, malformed or detected active-content PDFs are rejected.
Output
Produces one PDF containing every accepted source in the submitted order.
