How to Merge PDF Files Online
Our free PDF merge tool lets you combine multiple PDF documents into a single file directly in your browser. No registration, no upload to servers — your files never leave your device.
How it works: Select or drag your PDF files into the upload area, reorder them using the Up/Down buttons if needed, then click "Merge PDFs". Your browser will combine all the documents and download the result automatically.
Privacy: All processing happens locally in your browser using the pdf-lib library. Your documents are never sent to any server.
Supported files: Standard PDF files of any size (limited by your device's available memory).
