Combine PDFs into one, split one into many, or pull out just the pages you need. Nothing is uploaded.
Three of the most common PDF jobs in one place. Merge combines several PDFs into a single document in whatever order you arrange them. Split divides one document into several, either a file per page or in fixed-size chunks. Extract pulls out exactly the pages you name and leaves the rest behind.
Everything runs in your browser using pdf-lib, which means your documents are never uploaded, there is no file-size limit imposed by a server, no queue, no watermark and no sign-up. That matters more for PDFs than for most file types, because the documents people need to merge and split are so often contracts, statements, medical records and scans of identity documents.
