How PDF merging works
The tool copies pages from each selected PDF into a new document. It preserves the page order you set and downloads the result as merged-document.pdf.
What merging does not change
Merging does not edit text, reduce file size, repair damaged PDFs, or preserve every interactive form behavior. Password-protected or malformed documents may not load.
Privacy
Selected PDF bytes are read by JavaScript in this browser tab. The tool does not intentionally upload documents. Refreshing the page clears the selected files.
