Puts annoying watermarks on every page.

Using an api to convert text to pdf is unneccessary and unsafe. Literally everything you save can be accessed by PDFCrown. There is no guarantee they don't log everything you save.
This extension is completely free, but uses API -> costs money to keep up. Most often in situations like these you are the product and your data is sold.
I'd recommend to stay away and search for alternatives. The extension also watermarks the pdfs

Big Ugly Watermarks, Eww.
