Merge PDFs when separate forms, signed pages, reports, invoices, or appendices need to become one ordered document.

Treat the merged file as a final handoff copy and keep the original source PDFs available for comparison.
Sort the file list before merging and spot-check the first and last page of each source section in the output.
Open the merged PDF in a viewer and test important navigation because page numbers can change after combining files.
Unlock the file first if you have permission and confirm every source PDF opens normally before merging.
Merge in smaller batches or use a device with more memory for very large packets.
