How to Merge PDF Files for Free — No Software Needed

Most common reasons: sending one clean attachment, combining CVs and portfolios, merging monthly bank statements.

Privacy First

Most "free" PDF tools upload your files to their servers. Our PDF Merger runs entirely using pdf-lib in your browser. Zero bytes transmitted. You can disconnect from the internet and it still works.

Step-by-Step

  • Open the PDF Merger tool
  • Click "Add Files" or drag and drop your PDFs
  • Reorder by dragging file cards
  • Click "Merge X PDFs"
  • Downloads automatically — no email, no account
  • Tips

  • Large files: Handle PDFs totalling 200–300MB comfortably on a modern laptop
  • Password-protected PDFs: Open in your PDF viewer, print to PDF to create an unprotected copy
  • After merging, consider compressing the output if file size is large
