Questions about Interleave PDFs
Are files uploaded when I use Interleave PDFs?
No. PDF Care processes this tool locally in your browser, so the document contents are not uploaded to a PDF Care application server.
How many PDFs can I interleave?
This workflow accepts exactly two PDFs.
What if one PDF has more pages?
After the shorter PDF is exhausted, remaining pages from the longer PDF are appended in order.
