How to merge PDF
- Drop your PDF files, or choose them from your device.
- Drag the files into the order you want, or use the arrows. "Sort by name" orders 2-intro before 10-advanced.
- If a file is password-protected, type its password in its row and click Unlock.
- Optionally set a name, and tick "Password-protect" to lock the result. Then click Merge PDFs and download.
Questions
Is there a file size or page limit?
There is no limit set by us. Very large files depend on your device memory because everything runs locally.
Do you add a watermark?
No. The merged PDF contains only your pages.
Can I merge password-protected PDFs?
Yes, if you know the password. Type it in the file's row and it unlocks inside your browser. We cannot and do not guess passwords, and passwords are never sent anywhere.
Can I password-protect the merged PDF?
Yes. Tick the option, choose a password, and the result is encrypted with AES-256. It is off by default. If you forget the password it cannot be recovered.
Does merging remove restrictions like no-print or no-copy?
Yes. Files that only restrict printing or copying open without a password, and those restrictions are not carried into the merged file. Please use only files you have the right to use.
Does it work offline?
After the page loads, merging does not need the internet because nothing is sent to a server.
