Fácil de trabalhar no computador, no celular não gostei muito, as ferramentas não tem a mesma funcionalidade para editação e não tem opção de deixar em português.

It saved lots of time and energy trying to fiddle with other PDF apps. This one is great! Not only can I download my document and edit it, but what's cool is I can share and send my documents to anyone at any time in a quick and easy manner. It is so convenient!

Great for businesses.
Simple, yet powerful tool for anyone who finds themselves away from their desk often. I can easily fill in text fields, E-sign and add pictures to my pdfs. I've also used it to print, email or eFax pdfs and docs.

It is a bit frustrating to learn how to send it to my computer to be accessed and modified as needed. Right now it serves me as a trial, but I wouldn't pay for this.
2021-02-24
What do you like best?
Ability to edit pdf files and general ease of use
What do you dislike?
Limitations on how many files I can upload and the fact that it opens the files immediately, If I want to merge a newly uploaded files with previously saved files on my dashboard, it creates some unnecessary steps.
What problems are you solving with the product? What benefits have you realized?
Not really any problems - just a few areas the program feels clunky.
