How to combine several PDFs into one

Turn a stack of separate PDFs into one clean file, in the right order, with no watermark. Here's how, all in your browser.

A few signed forms, a cover page, some scans, and you want them as one clean PDF instead of five separate attachments. Merging puts them in order and gives you a single file.

How to do it

  1. Open Merge PDF and add the files you want to combine.
  2. Drag them into the order you want. This is the step people forget, so check it. The order in the list is the order in the final file.
  3. Combine, then download.

No watermark gets stamped on the result, which a lot of the "free" merge sites can't say. And the whole thing runs in your browser, so nothing uploads.

Getting the order right

The most common slip-up is a merged file with pages out of sequence. Before you combine:

  • Put the cover or intro page first.
  • Check any scans went in the right way up. If a page is sideways, fix it with Rotate PDF first.
  • Give it a quick scroll after downloading, just to be sure.

If the files are big

Merging several large PDFs makes a large PDF. If the result is too heavy to email, run it through Compress PDF afterward.
