How to Merge PDF Files Into One Document (Free & Private)

When Merging PDFs Saves You a Headache

Combining files appears constantly in everyday work:

• Invoices from 3 months into one file for GST filing
• Resume + certificates into a single PDF for a job application
• Scanned pages from different batches into one document
• Project files into a single PDF for client approval

The PDF Merger joins up to 20 PDFs in the exact order you place them — with no watermark and no upload to a server.

Step-by-Step: Merge PDFs

Step	What to do
1	Open the PDF Merger
2	Upload your PDF files (drag & drop, up to 20)
3	Drag to reorder into the final sequence
4	Optionally rotate or remove pages
5	Download the combined PDF

Everything happens in your browser, so confidential reports never leave your device.

Ordering Tips

The order you set is the order that prints:

• Put the cover page first, then content pages
• Use drag-and-drop — you can see page thumbnails as you go
• If you made a mistake, just remove and re-add a file before merging
