I like the service overall. The only improvement I could think of would be to work harder on Google integration with Authentication and Chrome apps. They usually work but it's frustrating when they don't work well.

Excellent cloud based software that I am able to use on any computer! Easily able to share between documents that are signed between multiple people. I love that I am able to use the software on any computer or phone with ease along with signing PDF documents! I would like if I could create boxes easier that were adjustable fields rather than just having a single section.

It's ok. While I rewrite the original words into another language, I want to down the line to look natural but it's not... because the line just leaves that much space

Easy addition This product has been very helpful for my needs. I like the ease of searching for a form, in my case an insurance form, and then filling in. The program makes it easy to edit boxes and save forms. The software is a little slow... there is a significant lag time opening each document, as well as saving and printing.

Glad to have it Glad to have it. Wished i didn't have to reset with every entry. It should assume you want the same font until you tell the program to change. Gets tedious to change for every number on the page.

They have been very prompt in getting back to me with any problems and questions. Sometimes, it takes two or more days, but eventually, they get back to me.

Perfect for merging multiple JPG images into a compact PDF This app / web page allowed me to easily merge six JPG image files (each 2550x3300 pixels, some included photos) into a single compressed PDF document that was small enough (7MB) to be easily shared as an email attachment. Did exactly the job I wanted it to!
