Your files stay on your device

Merging happens inside your browser, using the same engine the desktop app uses. The PDFs you choose are never sent to a server, which is why this keeps working once the page has loaded, even offline.

How to merge PDF files

  1. Drop your PDFs into the box above, or click to choose them.
  2. Drag the cards into the order you want.
  3. Select Merge PDFs, then download the combined file.

Frequently asked questions

Is there a file size or daily limit?

No. Because the work happens on your own device rather than on a server, there is nothing to meter.

Can I merge a password-protected PDF?

Yes. You will be asked for the password when it is needed. The merged file is not password-protected.

Are bookmarks kept?

Not yet. Bookmarks and form fields are dropped from the merged file; page content, layout and rotation are preserved exactly.
