Had an issue with billing today (a Saturday) however after emailing their customer service team I got a very quick response and kept getting help and support until the issue was resolved, on the same day. The person I was in contact with was very polite, understanding and genuinely wanted to help. The service itself is great and I would recommend it to any business that needs to edit and sign documents online .

He tenido una buena experiencia, pero lo único a mejorar que al realizar cualquier modificación queden alineados al texto, ya que al guardar el documento se pierde.

Why is my PDF file size so large?
Typically, there are two major reasons why PDF file size can be “disproportionally” large. The first reason is that one or more fonts are stored inside PDF document. Fonts can be subsetted and embedded right into PDF file. ... The second reason is using images for creating PDF file.
