When sharing information through the internet, nothing is more irritating than people who share information in uncommon formats, or let’s say: formats that you don’t use. Through the years, this problem has grown worse because every OS has it’s own text software that creates his own filetypes, his own media software that creates his own media extensions, etc. The best solution would be an open format that every platform should support, but that would damage some important monopoly positions, and who is going to decide which format is used? This is why there’s only one solution to the compatibility problem: converting from one format to the other. There’s some nice software to do this on the web, but the easiest software isn’t (spam)free, and you need quite some applications to be able to convert everything to anything. Luckily, web based convertors provide a better solution.
