I can use Preview app to select a region and crop a page. Can I do the same cropping for a whole pages in pdf? Are there tools (commercial or free) available for it?
I got a hint that works from this page
- Using the Sidebar, make it Thumbnails view, and Select All pages (Cmd-A)
- Select the area to crop using Tools > Rectangular Select
- Do the Tools > Crop (Cmd-K)
