Merge PDF Files

Combine several PDFs into one document, in the order you want.

Drop PDF files here or click to choose files

Drop in your PDFs, drag them into order, and get one document. There is no file-count limit and no size cap beyond your device’s memory.

Most free mergers copy the pages and nothing else: bookmarks vanish, links between pages stop working, and fillable forms turn into flat pictures of forms. Here, each file’s bookmarks, internal links and form fields come across with its pages, and duplicate field names are made unique so two copies of the same form don’t share answers.

Everything happens in your browser, which matters for the documents people usually merge: contracts, statements, applications.

How to use it

  1. Drop in your PDF files.
  2. Drag them (or use the arrows) into the right order.
  3. Click “Merge PDFs” and download the combined file.

Frequently asked questions

Are bookmarks and the table of contents kept?

Yes. Each file’s bookmarks are carried over and point at the right pages in the merged document.

Do fillable form fields still work?

Yes. Fields are carried across and registered in the new document. If two files have a field with the same name, the second one is renamed so they don’t mirror each other.

Can I merge password-protected PDFs?

Not while they’re encrypted. Open them with the password in your PDF reader and save an unprotected copy first.

Is there a limit on the number of files?

No fixed limit. Very large merges are bounded by your device’s memory, since everything is done locally.
