Merge PDF files

Merge PDF Files into One Document

The Merge PDF tool combines two or more separate PDF files into one new document. It is useful when reports, invoices, contracts, project sections, or supporting documents need to be kept and shared together. The tool creates a new PDF from the selected files, while the original files on your device remain unchanged.

How to Merge PDF Files

1. Prepare the PDF files you want to combine and make sure you select the correct copies.
2. Click the PDF files field and select two or more documents.
3. Click Submit to create the merged document.
4. Download and open the resulting file.
5. Check the page count and document sequence before sharing or using it.

The current interface does not provide a separate list for rearranging files after they have been selected. Review the merged result, and if the pages need a different sequence, use the Reorder PDF Pages tool.

Key Features of the Merge PDF Tool

Merge PDF vs Split, Reorder, and Extract PDF Pages

Use Merge PDF when you have several separate files and want to combine them into one document. Split PDF starts with one file and creates separate PDFs from the pages or ranges you specify.

If the document is already combined but its pages are in the wrong sequence, use Reorder PDF Pages. To keep selected pages together in one new file, use Extract PDF Pages.

Frequently Asked Questions About Merging PDF Files

Can I merge more than two PDF files?

Yes. The PDF files field accepts multiple documents. Processing time may vary according to the number of files, their sizes, and their page counts.

Can I rearrange the files after selecting them?

The current interface does not show a separate list for rearranging files after selection. Review the merged document, and use the Reorder PDF Pages tool if its pages need a different sequence.

Does merging PDFs also compress them?

No. The purpose of this tool is to combine pages, not reduce file size. The resulting file may be large because it contains the content of every selected document. After checking the merged file, you can use Compress PDF if you need a smaller version.

Will merging reduce page quality?

The merge process is not intended to lower image resolution or convert pages. However, the result still depends on the source files, so review the final document before using it for an official purpose.

Are the original PDF files changed?

No. The tool creates a new PDF and leaves the files stored on your device unchanged.

Can I merge a password-protected PDF?

You may need to open the document with the correct password and remove restrictions that prevent processing. The tool does not bypass passwords or document permissions.

What happens to forms, digital signatures, and bookmarks?

Creating a new document may affect interactive form fields, digital signature validity, or bookmarks. Open the result and test these elements if they are important to your workflow.

What should I do if the page order is wrong?

Use the Reorder PDF Pages tool to change the sequence inside the merged document.
