How to Merge PDF Files

Updated October 4, 2026

Combining several PDFs is useful when a report, application or project is spread across multiple documents.

Step 1: Prepare the document

Start with the files you want to combine, put them in the order you need, and use a PDF merge tool to create one document. Afterward, check the page order, bookmarks if applicable, and the final file size.

Step 2: Review the result

Open the finished document and check that the content, page order, formatting and readability match what you expected.

Step 3: Keep an original copy

For important documents, keep the original file separately so you can recover it if you need to make another version later.
