Fileminx is a browser-hosted application that will let you take care of the conversion of files such as documents, videos and images.
Just imagine this scenario.
Someone gives you a short clip that he has filmed using his iPhone at a show you wanted to attend but ended up missing. Yet, your usual media player can’t open it because it doesn’t support that mobile format. When that happens, you can head straight to the Fileminx website, upload the file and choose one that is more commonplace.
In the example, if the clip your friend had shot was a .MOV you can proceed to have it converted into an .AVI. The same goes for any image that is in a format you can’t view, or any document that was created using a word processor which is not that widespread. Just pick one of the most popular file formats available and that will be the end of it.
The site is entirely free to use, and you don’t have to sign up in order to convert anything. In that sense, it is an entirely open service. You have to make sure that the files you are submitting are smaller than 50 MB, but that’s all you will have to worry about.
