How to use Overlay PDFs
Choose a base PDF and an overlay PDF.
Set the overlay opacity.
Create the combined overlay PDF and check page alignment.
Overlay alignment
Overlay pages are drawn over base pages and scaled to the base page dimensions. If the overlay has fewer pages, its last page is repeated over the remaining base pages. This does not merge the two page sequences; review alignment when the documents use different layouts.
Processing and limits
Both PDFs are processed in your browser. Each file can be up to 100 MB and 2,000 pages.
