How it works
The PDFs are combined in the order shown in the list (remove and re-add to reorder), preserving each page's original content — text, images and formatting. Everything happens locally in your browser using the open-source pdf-lib library, with no file ever uploaded to a server.
Password-protected PDFs
Encrypted/password-protected files cannot be processed — remove the password before merging.
Frequently asked questions
Are my PDFs uploaded to a server?
No — everything happens locally in your browser. Files never leave your computer.
Is page order preserved?
Yes, each PDF contributes all of its pages, in original order, and the files are combined in the order they appear in the list.
Does it work with password-protected PDFs?
No — encrypted/password-protected files need to have that protection removed first.
