Merge PDF
Combine several PDF files into a single document. Drag to set the order. Everything runs in your browser — your files never leave your device.
How to merge PDF files
- Click the box above and select two or more PDF files (or drag them in).
- Reorder them by dragging if needed — the final PDF follows that order.
- Press Merge PDF and your combined file downloads automatically.
Is it private?
Yes. robinpdf merges your files directly inside your web browser using your own device's processing power. Nothing is uploaded to any server, so your documents stay completely private.
Frequently asked questions
Is there a file size or page limit?
There's no artificial limit. Because the work happens on your device, the only limit is your computer's memory.
Does it add a watermark?
No. The merged PDF is clean, with no watermarks and no sign-up required.
