How To Convert

  1. Upload PDF files. Upload two to twenty PDF files; total size and total page count are checked before processing.
  2. Set up the action on the page: merge pdf online. Check file order or selected pages before starting.
  3. Wait for the result. The output is one PDF with pages appended in the visible file order; Download all returns that PDF directly.
  4. Download the merged PDF and review it once: Password-protected or encrypted PDFs are marked as failed and excluded; if fewer than two valid PDFs remain, the job ends with a clear error.
