Do you know any app that can generate URL like Gyazo without uploading files?

Question

As far as I know, only Gyazo is possible.

Without Gyazo, imgur and sharex etc can generate URL.

Answer 1

Generate URL? 

URLs are simply addresses, much like your home, school or office. When you upload something to the internet, it automatically gets a URL address. Gyazo and all other social sharing sites are like that if you only care to understand how they work.
