Merge PDF files on Windows 10 and 11

Frequently asked questions
Is there a limit on how many PDFs I can merge?
No fixed limit. Because merging happens in your browser, the practical limit is your device's memory. Dozens of typical documents merge without trouble.
Will merging reduce the quality of my PDF?
No. Pages are copied as-is, so text stays selectable and images keep their original resolution.
Are my files uploaded anywhere?
No. The merge runs entirely on your device, so your documents are never sent to our servers.
