I wish I knew how to use it better, I need to send it to my car insurance company and I don't know how to send it effectively. I am interested in learning more.

I was looking for this solution. I work from multiple locations and multiple computers and using other pdf softwares that only allowed me to use the software on a certain number of registered devices was not a good solution for me anymore. I would have given this 5 stars, but I am still learning to use it, and I wish it was faster. In all fairness, the the lags may have to do with the processor in the chromebook I am primarily using it on right now which may not be that fast. It was an inexpensive device so it is very possible that my device is the reason for the slow transitions and not the software.

Best PDF Solution I work with PDF's every single day and that requires a software that can handle PDF files with ease and allow me to create and edit these on a moment's notice. PDFfiller is perfect for that. PDFfiller allows me to store private data fields (and documents) safely and share them with the right recipients knowing no one can intercept the private data on the way. My team and I often use the same templates on a daily/weekly basis, which saves us a lot of time all together. The interface itself is easy to use once you get the hang of things. All things considered, PDFfiller is an outstanding solution for all your business' PDF Needs. PDFfiller took a few days to learn the basic functionality of, but that is to be expected from a software that provides us with great value. I did not deduct any points for this as this is a very minor inconvenience.
