How Merge PDF Files works
Select several PDFs
Choose two or more files at once. The order you select them in is the order they appear in the final document.
Page copying
pdf-lib copies the pages out of each document into a new one, preserving every page's size, text and orientation.
One single document
The output is a single PDF with all pages joined end to end, ready to send or print.
