About this tool

Merge combines multiple PDF files into a single document in the order you choose. Pages are appended as-is — content, layout, and quality stay unchanged.

When to use this tool

  • Combine invoices or receipts into a single file
  • Merge separate chapters into one complete document
  • Assemble scanned pages from different sources into one PDF
  • Bundle related reports before sharing or archiving

Privacy

All merging runs in your browser. None of your PDFs are uploaded or stored.
