I have a PDF reader installed on Ubuntu. When I try to remove some pages, I print all pages to PDF except for the removing page. This will work except for the new file size is much bigger than the original file while a page is removed. How can I delete a page from a PDF without a file size increase in the output?
You can use pdfjam.
If you want to remove page 2 out of 5 pages, This is the way to use it:
pdfjam input.pdf '1,3-5' -o output.pdf
