How the PDF Merger Works
The tool copies the pages from each selected PDF into a new PDF in the same order as the files appear in the list. It uses PDF-LIB in your browser to read, copy and combine PDF pages. Your selected PDF files are processed locally in the browser rather than uploaded by this tool to a server.
