How to merge PDF files

  1. Add your PDFs — drop them into the box above or click Choose files. You can add more at any time.
  2. Put them in order — drag the files, use the ◀ ▶ arrows, or click Sort by name.
  3. Click “Merge” and download your combined PDF.

Nothing is recompressed or lost

The pages are copied into the new file exactly as they are: text remains selectable and searchable, images keep their original quality and page sizes don’t change. Merging a 10-page contract with a 2-page annex gives you a 12-page PDF that looks identical to the originals.

Need to change pages afterwards? Use Organize PDF to reorder, rotate or delete pages, or add a “COPY” stamp with the PDF watermark tool.

Private by design

Contracts, invoices, IDs and medical documents shouldn’t be uploaded to unknown servers. Here the PDFs are combined by your own browser: they never travel over the internet and we never see or store them. Password-protected PDFs need to be unlocked first.
