How merging PDF works

The tool copies every page from each PDF you upload, keeping the order shown in the list, and places them into a single new document.

Everything happens in your browser: files are never sent to a server, so you can use it with sensitive documents.

Worked example

If you upload 'contract.pdf' (2 pages) and 'appendix.pdf' (3 pages), the result is a single 5-page PDF with the contract first, followed by the appendix.

Frequently asked questions

How many PDFs can I merge at once?
There is no fixed limit: you can add as many files as you need, though very large documents may take longer to process.
In what order are the files merged?
In the order they appear in the list. You can remove a file and re-add it if you need to change the order.
Are my files uploaded to a server?
No. The whole merging process happens in your own browser, so your documents never leave your device.
Do I lose quality when merging PDFs?
No, pages are copied as-is, without recompressing or re-encoding their content.
