There is a time in every persons life when he needs to read a file which has the *.ps extension.
Most of the people I know download the useless programs: AFPL GhostScript and the GSView just to read or edit the cursed *.ps file.

I hate downloading programs which I am gonna use once in a life time (even 10 times drives me crazy).

From now on convert your files online through this website.
All you need to do:

1. Upload the ps file
2. press convert
3. download the new pdf file.

enjoy reading.
