I traditionally use Free PDF Tools from PDFill for this kind of task, but there is a download available today at giveawayoftheday.com for Foxonic Professional 4.0..
There is still 8 hours remaining to download and activate the program…
There is a very cool site at http://www.giveawayoftheday.com/
Fully free software is made available daily.
If you are interested in keeping an accurate record of time spent on projects, have a look at this site today, as the giveaway is http://www.giveawayoftheday.com/simple-task-timer/ (but only for 8 more hours!)
Here is the RSS feed link.
