Combine documents without uploading them
Join reports, invoices or assignments in file order. All pages from the first PDF precede the second PDF. Reorder files before merging.
A practical example
For a report and its appendix, place the report first. If only some appendix pages are needed, extract them with Split PDF before merging.
