Frequently Asked Questions
Yes, there's no limit on how many files you combine — add as many as you need in a single session.

About PDF Merge
PDF Merge combines two or more PDF files into a single document, in the exact order you choose. It's built for the everyday task of assembling scattered files — invoices from different months, a signed contract plus its appendix, chapters of a report, or scanned pages from separate sessions — into one clean file to send or archive. Merging happens locally in your browser, so your documents are never uploaded anywhere.
