The first time I downloaded the software, I mistakenly selected the one for use with Microsoft and all features did not work on my Chromebook. After going back I found the correct program for use with Chrome. The only problem I still have is creating my signature which I have described below under features to add.

This has been my favorite pdf program of all time. I do not work I am a happy homemaker and have a special needs son and have a lot of documents to file and fill and fax for him. This is the best program. The price is a bit high for me but it's worth it at times when I need to do something that other pdf programs just can't do it.

What do you like best?
That I am able to take any non-fillable pdf document and make it fillable.
What do you dislike?
I find the ease of use of the website decreased with the updated version. Not impossible, but less ease of use. Nothing too bad.
What problems are you solving with the product? What benefits have you realized?
I use pdfiller in all aspects of my job where non-fillable documents are not available. From Business Management to Human Resources.

It's a great experience and many options to get your forms completed in the manner you want them done. The option to save them for later and email them to others to edit is definitely a perk!
