or drop them anywhere on this page

Your file stays on this device. Nothing is uploaded.

Put files together

Choose several PDFs at once, or drop them on the page together: they open as one document, one file after another. To add more later, press "Add pages" under the thumbnails or the button with a page and a plus sign in the bar, or drop a file between two thumbnails and its pages are added right there.

In the order you want

Drag pages across the whole document after adding them, and delete the ones you do not need.

Links keep working

A table of contents that links to pages of the added file goes on leading to them.

Files with passwords

A protected file is added after you enter its password. Files opened together make a document without a password, until you set one. Pages added to a protected document you have open are saved under that document’s password.

Questions and answers

How many files can I merge?

As many as you like, all at once or one after another. The merged document has to stay under 2 GB.

Do the added pages keep their forms?

They keep what the fields show. Fields of an added file become part of the page and can no longer be filled in.

Are my files stored somewhere?

Not on a server. They are put together by your browser on your own device. Until you save, the merged document is kept in your browser’s storage on that device, like any unsaved changes, so that it is not lost if the window closes.
