      Your files never leave this page — all processing happens locally with the open-source pdf-lib library.

      Merge and split PDF files privately, right in your browser

      This free PDF merge and split tool runs entirely on your device. When you merge, the selected PDFs are stitched together in the order you arranged them. When you split, you enter a page range like 1-3,5 and get back a new PDF containing only those pages. Because everything happens client-side with pdf-lib, your documents are never uploaded to a server — making this ideal for contracts, statements, and any sensitive paperwork.

      Common uses include combining scanned receipts into a single file, extracting a signature page from a longer agreement, or trimming a report down to the pages you actually need to share. There is no signup, no watermark, and no page limit beyond what your browser's memory allows.
