I want to create a website like [https://www.pdftoword.com/ or [URL="http://www.clipconverter.cc/"]http://www.clipconverter.cc/](https://www.pdftoword.com/)using PHP.
For this purpose, what should i do?
1> Do i need to create a software and install that on server to convert a file? Then after uploading that file to server and then by using that software for conversion and giving it back to user using link?
I want to know the procedure for creating these kind of services.
