About this tool

Combine complete PDF files in one order

Merge PDF builds one document from every page in the files you select. You control the file order before processing, and the original PDFs remain unchanged.

Useful for

  • Join report chapters, invoices, or application documents.
  • Put separately scanned sections into one submission.
  • Reorder whole files without manually selecting every page.

Good to know

  • Page dimensions are preserved; an optional page rotation is added to that page's existing orientation.
  • Password-protected or unreadable PDFs must be unlocked first.
  • The combined file is created locally in this browser.
