About Merge PDF

Combine two or more PDF files into a single document. Drag to reorder files before merging — everything happens locally in your browser, so your documents are never uploaded to a server.

Benefits

  • Combine reports, invoices or scanned pages into one file without installing software.
  • Files are processed locally, so nothing is uploaded to a server.

Common mistakes

  • Forgetting to reorder files before merging, resulting in pages in the wrong sequence.
  • Merging password-protected PDFs, which this tool cannot open without the password.
