About this tool
Our free PDF merger combines two or more PDF files into one tidy document in seconds. It is the tool you reach for when you need to join scanned contract pages, bundle invoices for an expense claim, or assemble chapters, reports, and forms into a single file before emailing or printing. Unlike iLovePDF and Smallpdf, which cap free users at a couple of tasks per hour, GetFreeToolsAI has no daily limits and never stamps a watermark on your output. You can add as many files as you like and drag them into the exact order you want before merging. Everything runs locally in your browser using pdf-lib, so your documents are never uploaded to a server — your confidential files stay entirely on your device. It works in Chrome, Firefox, Safari, and Edge with no installation and no signup, ever.
