It is a PDF editor very easy to use and very useful!

It has helped me a lot to edit PDFs and very easily, when before it was impossible.

Pros

You can upload a document from your computer, but also from Dropbox, Box and OneDrive. With any option, you can edit by adding images, signatures, text boxes and brands.

Cons

As a disadvantage, the file load is a bit slower than other editors. however, it provides great editions.
