How to Merge PDF Files into One
Contracts with annexes, scanned forms, monthly reports — business paperwork rarely comes as one tidy file. Merging combines several PDFs into a single document in the order you choose, which makes files easier to send, store and print. This guide walks through merging with a free browser-based tool: nothing is uploaded, so even sensitive documents stay private.
Step by step
- Open the Merge PDF tool and add all the files you want to combine.
- Check the list order — the merged document follows it exactly. Remove anything added by mistake.
- Click Merge and wait a moment while the pages are joined.
- Download the single combined PDF and open it once to confirm the page order.

Tips for better results
- Rename files with numbers first (01-contract.pdf, 02-annex.pdf) if you merge the same set regularly — the order is then obvious.
- Merge first, compress second: if the combined file is too big to email, run it through a PDF compressor afterwards.
- Scanned pages merge exactly like digital ones; merging does not change quality.
Frequently asked questions

No. Pages are copied into the new file exactly as they are — text, images and resolution are unchanged.
The file must be readable in the browser first. If a PDF asks for a password to open, remove the protection in the app that created it, then merge.
