When merging several PDFs helps
Merging PDFs is one of the most common document tasks: bundling several scanned invoices into one submission, combining report chapters that arrived as separate files, or putting together a full dossier (cover page, contract, appendices) as a single document that's easy to share. Doing it with this tool avoids installing desktop software or paying for a subscription just for that one-off task.
Order matters
The final PDF respects the order you leave the files in the list, top to bottom — and within each file, the original order of its pages. If you need to reorganize loose pages (not whole files), try splitting the PDF first into the parts you need and then merge them in the right order.
Frequently asked questions
Is my PDF uploaded to a server?
No. The whole merge process happens inside your browser. Your files never leave your device.
How many PDFs can I merge at once?
There's no fixed limit — it depends on your device's memory. It works well with dozens of normal-sized files.
Can I change the order of the files?
Yes, use the ↑ and ↓ arrows next to each file in the list to reorder them before merging.
Does merging lose any quality?
No. Pages are copied as-is, without recompressing or re-encoding anything.
Does it work with password-protected PDFs?
No, an encrypted PDF can't be read in the browser. Remove the password first with your regular PDF reader.
