What this tool does
Combine several PDF documents into one file in the order you choose. This is useful for joining a signed cover sheet, supporting documents and an appendix before sending one complete attachment.
- What you can open
- Two or more PDF files that can be opened without a password.
- What you will download
- One PDF containing the selected documents in their chosen order.
How to use it
- Add the PDFs that belong in the final document.
- Move files up or down until their order matches your intended reading order.
- Run the merge, download the combined PDF and check the join between documents.
Know the tradeoffs
- Merging does not rewrite page content or make different paper sizes identical.
- Changing a document can invalidate existing digital signatures.
Questions about this tool
Can I choose which file comes first?
Yes. The file list determines the order in the merged document.
Will pages with different sizes be resized?
No. Use Resize PDF separately if you need one paper size throughout.
