Frequently Asked Questions

1. How can I merge PDF files online?

Add at least two PDF files, arrange them in the desired order, and click “Merge PDFs & Download.” The tool combines the documents and downloads the resulting PDF.

2. Is this PDF merger free?

Yes. The tool is designed to merge PDFs without a subscription or account. Your browser and device must have enough resources to process the selected files.

3. Are my PDF files uploaded to a server?

The merging operation is performed in your browser, and the tool does not send the selected PDF contents to an OffSecPath server. The PDF processing library is downloaded from a third-party CDN.

4. Can I change the order of the PDF files?

Yes. Use the up and down arrow buttons beside each document to arrange the files before merging. The combined PDF follows the order shown in the list.

5. Can I merge password-protected PDFs?

This tool may not be able to open encrypted or password-protected PDFs. Remove the password using an authorized method before merging the documents.

6. Will merging reduce the PDF file size?

Not necessarily. Merging combines documents into one file; it does not automatically compress the contents. Use a PDF compression tool if you need a smaller file.
