Common questions
How do I combine PDF files into one?
Add the PDFs, arrange them with the arrow buttons and select Merge PDFs. The download contains every page of every file, in that order.
Does merging reduce the quality?
No. Pages are copied into the new file without being redrawn or compressed, so text stays sharp and selectable.
Can I merge PDFs from different folders?
Yes. Each time you choose files they are added to the list, so you can pick PDFs from several folders before merging.
Are my PDFs uploaded?
No. The PDFs are merged in your browser, and they are never sent to our server or anyone else.
