Other ways to do it
On a Mac, Preview can merge PDFs by dragging thumbnails between windows, which is fiddly for many files. Online tools work but upload your documents and often limit free use.
Questions
Is there a limit on files or pages?
No. Fileshaper has no limits.
Can I merge password-protected PDFs?
Remove the password first; Fileshaper will tell you which file is protected.
Will the text still be selectable?
Yes. Merging copies pages exactly; nothing is turned into an image.
