Options after selecting a fileFrequently asked questions
The details, when you need them.
Can I merge PDFs with different page sizes?
Yes. The combined PDF keeps the sizes of the copied pages. Review the print settings if you want to print mixed sizes.
Can I reorder pages inside a file?
Use Organize PDF to move individual pages. Merge PDF orders complete files.
Build a document that is easy to follow
Put the cover sheet first, supporting information next and appendices last. The file list controls the order of whole documents. If you need to interleave individual pages, use Organize PDF instead. The double-sided option inserts a blank page when needed so the next document starts on a right-hand page.
What happens to the original pages?
Pages are copied into a new PDF without turning them into pictures. Different page sizes can coexist in the result. Review forms, bookmarks and links after combining documents because document-level features may not transfer exactly. Keep the source files if you need to edit or verify them later.
Copied document features
Document-level bookmarks, signed status and form behavior need checking after pages are copied.
A section begins on an unexpected sheet
Odd-page starts may have inserted a blank page. Check the option and repeat without it for a digital-only packet.
