Run tool
This online PDF merger combines two or more PDF documents into a single organized file. When managing invoices, quarterly reports, scanned paperwork, or multi-part project briefs, keeping related materials in one continuous document simplifies document distribution and long-term recordkeeping.
To assemble your file, select and upload the PDF documents in the exact order you want them to appear. The tool processes each file sequentially, appending every page while preserving the original layout, orientation, and internal page order. After processing completes, the result panel provides your combined PDF ready for download, along with summary counts showing the total number of files merged and pages processed.
To perform a merge, you must supply at least two valid PDF files. Providing damaged files, non-PDF formats, or fewer than two documents stops the process and displays an error message explaining the issue. Use this tool whenever you need clean, consolidated files for submissions or archiving.
Instructions
- Select and upload at least two PDF files in the sequence you want them joined.
- Check that the documents are arranged in your desired order.
- Run the merger tool to process and combine the documents.
- Download your newly combined PDF document from the result panel.
Examples
- Merging two 5-page PDF contracts creates a single 10-page document with pages 1 through 5 from the first file and pages 6 through 10 from the second file.
- Combining a 1-page cover sheet, an 8-page project proposal, and a 3-page budget estimate yields one continuous 12-page PDF file.
FAQ
How many PDF files must I supply?
You must supply at least two PDF files. If you provide fewer than two files, the tool cannot perform a merge and reports an error.
Does the tool change the order of pages inside my files?
No. The merger maintains the exact internal page order of each document, appending the contents of each subsequent file to the end of the previous one.
What happens if one of the selected files is corrupted or invalid?
If any uploaded file is unreadable or not a valid PDF, processing stops and an error message is displayed so you can replace the problematic file.
