Combine multiple PDFs into one file

About Merge PDF

Combine several PDFs — a resume and cover letter, scanned receipts, or chapters of a report — into a single file you can send or file away. It's the quickest way to stop juggling a dozen separate attachments.

How to merge pdf

  1. 1Upload two or more PDF files — you can select several at once or drag them all onto the dropzone.
  2. 2Files are combined in the order you added them, so re-add them in the right sequence if needed.
  3. 3Click Run Merge PDF to combine the files.
  4. 4Download the single merged PDF once it's ready.

Tips

If a page comes out sideways after merging, run the result through the Rotate PDF tool to fix it.

A merged file can end up large if it includes scanned pages — run it through Compress PDF afterward if you need to email it.

Merging works best when all your files are already right-side up and in the correct page order.
