Free PDF Merger

Combine multiple PDF files into one, privately in your browser.

Add several PDFs, put them in the order you want and join them into a single file. It is a tidy way to send one application pack or invoice bundle instead of five attachments.

How to use the PDF Merger

  1. Add your file. It opens instantly in your browser, so large contracts stay private.
  2. Choose the options for the change you want, such as pages, position or format.
  3. Download the result. The original file is never modified, so you can always start again.

What is the PDF Merger?

Merging combines several PDFs into one document in the order you choose, which is ideal for sending a single application, invoice pack or report.

Signplify tools run in your browser, so there is no signup, no watermark and no limit on how often you use it.

Getting started with the PDF Merger

Using the pdf merger takes a minute or two. Your progress is saved in this browser, so you can come back later.

Tips for better results

Rename files so they sort sensibly before adding them, then use the arrows to fine-tune the order.

Merge first, then add page numbers with our page number tool for a clean combined document.

Privacy and where your data goes

Documents and files you use here are processed on your own device. Signplify does not receive what you type or the files you open, which makes it suitable for sensitive information. If you clear your browser data, any saved draft is removed.

Frequently asked questions

Can I change the order of the PDFs before merging?

Yes. Add the files, put them in the order you want and then join them into one PDF.

Is a merged PDF uploaded anywhere?

No. The files are combined in your browser, so private documents stay on your device.
