Frequently asked questions about merging PDFs
Are my files stored on a server?
No. Your PDFs are not sent to a server or external API and are processed only inside your browser.
Can I change the file order?
Yes. Drag files into the order you want. They are merged from the top of the list to the bottom.
Can I merge password-protected PDFs?
Password-protected PDFs are not supported yet. Please try again with an unlocked copy.
Are all advanced PDF features preserved?
Ordinary visible page content is retained, but digital signatures, bookmarks, forms, attachments, layers, some annotations, and special metadata may not be preserved completely. Editing a signed PDF can invalidate its existing digital signature.
