Combine PDF Files into One Document
Use this PDF merger to join two or more PDF files into one document. Add the files, check the first-page thumbnail and page count for each, then move files up or down until they are in the order you want. The output follows that file order.
The PDFs are combined in your browser without uploading the document contents for merging. Download the merged PDF, or select Compress this PDF if the result is too large for an email or upload limit. Keep the originals so you can change the order or make edits later.
What You Can Do Before and After Merging
Choose the File Order
Use the up and down controls to place cover pages, chapters, or attachments in the correct sequence.
Check the Inputs
Review file names, first-page previews, and page counts before creating the combined PDF.
Download One PDF
Send one file instead of several attachments when the recipient asks for a single document.
Compress the Result
Use Compress this PDF after merging to carry the result into the compressor and check its actual size.

Will Merging Make My PDF Smaller?
Merging joins pages into one PDF; it is not a compression step. The combined file may be larger than a portal or email limit. After merging, choose Compress this PDF and compare the resulting file size and readability before sending it.
Does Combining PDFs Change Page Quality?
The merge operation copies PDF pages without rasterizing them or deliberately reducing image resolution. Check the downloaded file if your sources contain forms, links, or other interactive elements, because combining PDF documents does not guarantee every document-level feature survives unchanged.
