How to merge PDF files

Merging PDFs is useful when you need one final document from reports, scanned pages, invoices, assignments or application forms.

1. Collect the PDF files

Choose the documents you want in the final file. Make sure they open correctly before merging.

2. Decide the order

The order matters. Put cover pages first, followed by the main document, appendices and supporting files.

3. Merge the files

Use the PDF Merge tool to select the files and create one combined document.

4. Check the result

Open the merged PDF and check page numbering, orientation, bookmarks and important signatures.

Privacy tip

For sensitive documents, prefer a workflow that processes files locally in your browser when practical.
