I want to convert a PDF from version 1.5 to 1.4 using a command line utility.
Is there anything available?

Found this in the ubuntu forums :
# gs -sDEVICE=pdfwrite -dCompatibilityLevel=<VERSION> -dPDFSETTINGS=/screen -dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf input.pdf
Just tested this and it works fine, I'll post some output now.

1Just noticed that the example is backwards.. 1.4 -> 1.5 instead of 1.5 -> 1.4 . ah well, thanks for the up votes :) – lyarwood – 2009-08-19T15:03:01.463
Not a problem. I worked that out :P – Tom – 2009-08-19T15:18:49.390
