Upload multiple PDFs, see every page as a thumbnail, drag to reorder across files, then merge and download. Everything runs 100% in your browser — your files never leave your device.
PDF Merge combines two or more PDF files into a single document, right inside your browser — no upload, no watermark, no page limit, and no sign-up.
Drop in as many PDFs as you like, rearrange the pages into the exact order you want (even interleaving pages from different files), drop any you don't need, and download one clean, combined PDF. It's the everyday fix for scattered paperwork:
Because everything is processed locally with pdf.js and pdf-lib, sensitive documents — contracts, medical records, bank statements — never leave your device, which is exactly what most online "free PDF merge" sites can't promise.
The result is a proper vector PDF, not a flattened image: text stays selectable and searchable, embedded fonts are preserved, and images keep their original resolution. It's the quality you'd expect from desktop software like Acrobat Pro, without the subscription or the install.
merged.pdf.No. Files are read with pdf.js, rendered as thumbnails, and merged with pdf-lib — all in your browser. Nothing is uploaded, logged, or transmitted, so confidential PDFs (contracts, medical records, financial documents) stay completely private.
Yes — that's the whole point. Every page from every uploaded PDF appears as its own draggable thumbnail. You can interleave pages from different files in any order, and hover any card and click × to exclude that page from the merged output.
No. Pages are copied at the vector level — text stays searchable, embedded fonts are preserved, and images keep their original resolution. The output is equivalent to what desktop tools like Acrobat Pro produce, just without the subscription.
There's no fixed limit. Because the work happens on your own device, the practical ceiling is your computer's memory rather than an artificial cap. Most everyday jobs — dozens of files and hundreds of pages — merge in seconds.
Yes. The tool works in any modern mobile browser on iPhone and Android. Tap to select your files, drag thumbnails to reorder, and download the merged PDF straight to your device — no app to install.
Never. There are no watermarks, no daily limits, and no paywall. The merged PDF is yours, clean and complete, every time.
You'll need to remove the password first, since encrypted files can't be read without it. Once a PDF is unlocked and opens normally, you can merge it here like any other file.
