Show HN: bindPDF.app - Combine multiple PDF files into a single file on macOS
github.comYou can do this with Preview.
Yep! Here is the how-to guide for those curious:
I've always been partial to `gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=merged.pdf *.pdf`.
gs is installable via homebrew.
If this interests you, I would suggest PDFsam.
It has a lot of actually really useful pdf slicing features, like alternate merge (for merging both sides of scanned documents into one).
