Combine multiple PDF files into one document — free, fast & private
PDF Merger combines several PDF files into a single document, all directly in your browser. Drop the files, drag them to set the order, and click merge — the output downloads in seconds. Because every page operation runs locally with pdf-lib, your contracts, scans, financial records or medical reports never leave your device. Use it whenever you need to assemble a coherent file out of multiple sources: combining receipts before submitting an expense report, stitching scanned ID pages, packing a job application into one PDF, or grouping research papers for offline reading. Pages keep their original quality, fonts, links and form fields intact — there is no re-rendering and no compression unless you ask for it.
