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.
