Our free PDF merger is a powerful online tool designed to help you combine multiple PDF documents into a single file quickly and securely. Whether you need to merge reports, invoices, contracts, or scanned pages, this browser-based solution handles everything without requiring software installation or user registration.

Unlike desktop applications that require downloads and updates, this online PDF merger works instantly in any modern web browser. The tool utilizes advanced JavaScript libraries to process your files locally, ensuring that sensitive documents never leave your device.

How Our PDF Merger Works

The merge PDF process is straightforward and user-friendly. First, upload your PDF files using the drag-and-drop interface or file selector. You can upload multiple documents simultaneously. Once uploaded, arrange them in your desired order using the up and down arrows. Finally, click the “Merge PDFs” button to combine them into one cohesive document.

The underlying technology uses PDF-Lib, a powerful JavaScript library for creating and modifying PDF documents. This ensures compatibility with all PDF standards and maintains the quality of your original files during the merger process.
