Merging multiple PDF files into a single document is a common task for business, academic, and personal use. Our free PDF Merger combines multiple PDF files in your specified order — all processing happens in your browser.
The tool uses the pdf-lib library to read, merge, and create PDF files entirely client-side. Your documents are never uploaded to any server, making it safe for confidential, legal, and personal documents.
Simply upload two or more PDF files, arrange them in the desired order, and merge. The result is a single PDF containing all pages from all files. Download the merged PDF instantly.
