Anyone who has never even used a computer before can go to one of these websites, follow the instructions on the screen in front of them, and get it done. Zero experience or skills required.

No they don’t. People who have never used a computer before have trouble even using the mouse. They don’t know what a file is, they don’t know what a filetype is, they don’t know that you can convert one type of file to another, they don’t know even to look for a file conversion website, they don’t know how to upload a file to a website, they don’t know how to find a file in the file dialogue, and on and on. Seriously what are you on about?
