About the Merge PDF

Merge PDF joins two or more PDF files into a single document. You can reorder the files before merging, and all pages keep their original size, text and quality. The merge happens inside your browser, so confidential documents are never uploaded.

How to use the Merge PDF

Drop your PDF files into the box or click to choose them.
Use the up and down arrows to put the files in the order you want.
Click "Merge PDFs" and download the combined document.

Frequently asked questions

Is there a limit on the number of files?

There is no fixed limit. Very large documents depend on your device memory; dozens of normal PDFs merge without problems.

Will the quality change?

No. Pages are copied as they are, so text stays selectable and images keep their original quality.
