I want to use a custom font on my website.
I have found the woff file of this font on another website who was using it. I've saved it on my computer, tested it on my website (localhost only) and it works. However, after some research, I found that multiple website are selling this font.
So I'm wondering, can I use the woff file on my website just like this (probably not)? If I simply buy the font, is it enough to use it on my website or should I obtain some kind of special license to do so ?
I don't intend to sell the font so I'm not sure it is relevant but I'm talking about a commercial website. I don't know if it can be considered as a commercial use or not.
Lastly, the web-font I'm talking about is sold on the following website:
