Everything below happens on your own device, so the size of your files is limited by your hardware rather than an upload allowance. Step 01 ### Add the PDFs you want to combine Step 02 ### Drag the files into the order you want Step 03 ### Merge and download your single PDF ## Why Choose This Free PDF Merger? Merging PDFs usually means handing a stranger's server your contracts, invoices or medical records for a task that takes a second. This tool removes the server from the equation entirely. ### Your documents never leave your device Most online PDF mergers upload your files to a server, merge them there, and ask you to trust their retention policy. This one does the whole job inside your browser tab, so there is nothing to retain. ### No queue, no upload wait Because there is no round trip to a server, merging starts the moment you click. Large files are limited only by your own device, not by an upload cap or a free-tier throttle. ### Free, with no watermark or page cap No signup, no daily limit, no branding stamped onto your pages. The merged file is exactly the document you assembled, and nothing else. ## What You Get From Combining PDFs Here One file is easier to send, sign and archive than eight. These are the practical differences you should expect from the merged document. ### Lossless page copying Pages are copied across as they are, with no recompression. Text stays selectable and searchable, and images keep their original resolution. ### Two files or two dozen Combine a signed contract with its annexes, stitch scanned receipts into one expense report, or assemble a portfolio from separate exports -- in one pass. ### Order you control Drag any file to reposition it, or use the up and down controls for precise, keyboard- and mobile-friendly ordering. The output follows your sequence exactly. ## Frequently Asked Questions Everything you need to know about merging PDF files with DragBin. ### Is this PDF merger really free? Yes. Merging PDFs with DragBin is completely free, with no signup, watermark, or page limit. ### Are my files uploaded to a server? No. Every file stays on your device. The merge runs entirely in your browser, so your documents are never uploaded, stored, or seen by anyone. ### How many PDFs can I combine at once? As many as you like. Add two files or two dozen -- drag them into the order you want, then merge them into a single PDF. Very large batches are limited only by your device's memory. ### Can I change the order of the files? Yes. Drag any file by its handle to reorder it, or use the up and down controls. The merged PDF follows the order you set. ### Does merging reduce the quality of my PDF? No. Pages are copied across as they are, with no recompression, so text stays selectable and images keep their original resolution. ### What happens to bookmarks and form fields? The visible content of every page is copied exactly. Document-level extras -- bookmarks and interactive form fields -- are not carried into the merged file, so the result is a clean, flat document. ### Does it work on my phone? Yes. The tool is fully responsive and works in any modern browser on desktop, tablet, or mobile -- nothing to install on Windows, macOS, Android, or iOS. ### What about password-protected PDFs? Remove the password from the PDF first, then add it here. Encrypted files can't be merged, because the tool never asks for your password. ## Store and share your merged PDFs securely Pair this free tool with zero-knowledge, post-quantum cloud storage. 25GB free, forever -- no credit card.
