About PDF Merger
PDF Merger lets you combine multiple PDF documents into a single file entirely in your browser using the PDF-lib library. No files are ever uploaded to a server — all processing happens locally on your device, which is important when you are working with confidential documents, contracts, or financial statements.
You can drag and drop as many PDFs as you need, reorder the pages, and download the merged result in seconds. This is useful for combining reports, assembling multi-chapter documents, or merging scanned pages that were saved separately.
The tool works entirely offline after the page has loaded. It handles most standard PDF files including text, images, and mixed content. Very large files may take a moment to process depending on your device.
