Example
Two one-page PDFs become a two-page PDF.
Frequently asked question
Are signatures preserved?
No. Editing a signed PDF invalidates its signature; use an unsigned source.
Limits and privacy
Combined input is limited to 25 MB and 200 pages. Encrypted or malformed PDFs are rejected. Forms, annotations, links and signatures are not guaranteed to survive unchanged; digital signatures are not preserved as valid.
