WIP Alert This is a work in progress. Current information is correct but more content may be added in the future.
Select one page
You have a file multipage.pdf and you want to extract the first page into a new file page1.pdf:
$ qpdf multipage-file.pdf --pages . 1 -- page1.pdf
Select multiple pages
You have a file multipage.pdf and you want to extract pages 1 to 5 page into a new file pages1-5.pdf:
$ qpdf multipage-file.pdf --pages . 1-5 -- pages1-5.pdf
Compress PDF file
Generate an optimized (smaller in smaller) version of input.pdf.
Other options to try out:
--recompress-flate--optimize-images--compression-level=N(wherenis an integer)
$ qpdf --compress-streams=y --object-streams=generate input.pdf output.pdf
Merge multiple pages into one file
TODO
Add password fo PDF file
Passing the password twice in the command is not a typo. Owner password VS user password
Add password "foobar" to file file.pdf, creating a new file called file-encrypted.pdf:
$ qpdf --encrypt foobar foobar 128 -- file.pdf file-encrypted.pdf
Add password to PDF file, inplace
If you don't want to create a copy of the file with password, but modify the file inplace instead:
Use --replace-input modifier, using "foobar" as the password:
$ qpdf --replace-input --encrypt foobar foobar 128 -- file.pdf
Remove password from PDF file
Use --decrypt and provide the password to generate a copy of the file, without password
$ qpdf --decrypt --password=foobar original-file-encrypted.pdf file-decrypted.pdf
