Combining multiple PDF documents into a single file is a frequent need in business, academic, and legal contexts. Whether you are assembling a report from multiple sections, combining signed contracts, or creating a unified document package, DaConvert's PDF Merger makes it simple.
The tool uses pdf-lib to concatenate PDF files while preserving the formatting, fonts, and images in each original document. Simply upload your files, drag to reorder them as needed, and merge. The resulting PDF contains all pages from all input files in your specified order.
Processing happens entirely in your browser, which is critical when working with sensitive documents. Legal contracts, financial reports, and confidential business documents are never uploaded to any server during the merge process. No file count or size limitations beyond your device's available memory.
