Frequently Asked Questions

How do I merge PDF files online for free?

Upload two or more PDFs to pdfGens PDF Merger. They appear in a list — drag to reorder if needed. Click Merge PDFs and download your combined PDF instantly.

How many PDF files can I merge at once?

There is no hard limit. You can merge as many PDFs as your browser's memory supports. Most users merge 10–20 files without any issues.

Can I merge password-protected PDFs?

pdfGens attempts to merge password-protected PDFs using the ignoreEncryption flag. If the PDF has a complex password, you may need to remove the password first using our PDF Protect tool.
