One thing about utility is it never ceases to exist as long as the conditions are perfect, something like PDF converter was a repercussion of Adobe acquiring the market of a new format via Windows and one day Windows decided not to include Adobe suite in Windows. That's what crashed the complete cycle, now there are millions of PDFs in circulation with gigabytes of information but latest version of Windows doesn't contain any stuff to edit, compress, convert them atleast not to a normal person who's the real consumer. Plus there comes the point of charge required just to convert information in same medium which some people don't agree on paying hence this type of tools will exist till the dawn of computer
