Merge PDF files in your browser

Merging is useful for assembling applications, reports, scanned pages and invoices into a single document. Files are joined in the order listed, so check the numbering before you merge.

If a file is rejected, the message tells you why — for example because it is not a real PDF, is damaged, or is password-protected.

Key Highlights:

  • Reorder with up/down buttons
  • Real page counts per file
  • Clear error for invalid or protected files
  • Direct download of merged.pdf
