Combine PDFs without the hassle or the risk
Merging PDFs is one of the most common office tasks: putting invoices, contracts, annexes or report chapters into a single file that is easy to send. Many websites ask you to upload your documents to their servers, which is a bad idea when they contain personal or financial data.
Here the merge happens inside your browser. Files are read on your device, combined page by page, and the result is downloaded directly. If you close the tab, no trace of your documents remains on any server.
You can add up to 20 files of up to 50 MB each, with a 200 MB total. If you need the opposite operation, use our split PDF tool to extract pages by range.
Frequently asked questions
- Are my PDFs uploaded to a server?

- Is there a limit on files or size?
- You can merge up to 20 files, 50 MB each at most and 200 MB in total. There is no limit on merges per day.
- Can I change the order of the documents?
- Yes. Drag each PDF or use the arrows to reorder them before merging. The position number updates instantly.
- Does the final PDF have a watermark?
- No. The combined document stays clean, with no marks, ads or footers added.
