How to Merge PDF Files Into One

To merge PDFs, open the Merge PDF tool, add two or more files, arrange them in the order you want and merge. The combined PDF is created in your browser, so your documents are never uploaded.

How to use the Merge PDF

  1. Add the PDF files.
  2. Arrange them in the order you want.
  3. Click merge.
  4. Download the combined PDF.

Worked example

Merging a 3-page contract and a 2-page appendix gives one 5-page PDF, contract first.

Tips and common mistakes
