Hello. Is there a tool existing that can reduce image dimension by
removing empty spaces?

I can read that question in 2 ways.

The first is to remove the 'frame' that is not actually part of the
picture. The second is to reduce the file size.

If the latter, then change the coding. Loose resolution. Look at
'run-length encoding'. Remove stenographic content. Posterise or
reduce the numbers of colours.

Is the key issue here 'reduce' as in shrink' or 'empty spaces'?
If the latter, how do *you* define an 'empty space'?

Side question: Is English your native language? If not, perhaps you
might care to rephrase the question or expand on what you mean and are
trying to achieve.

The biggest problem a security consultant has is getting managers to
perform regular risk assessments. They don't want to hear that it's an
on going process. The attitude was "why bother if I can't just check it
once and be done with it".
