See for yourself by reading reviews on the most popular resources:
It is very easy to use although there are somethings I don't understand what they are for. Other than that this is the easiest most convenient way to submit forms without the other party having to try to read your own writing.

My wife had some US Government forms that needed to be filled out and returned. Because of her medical condition, she couldn't fill them out longhand, and she asked me if there was a way she could type and fill them in. We couldn't find access to a typewriter (WHAT'S THAT???), but I searched on Google and found information about your app. I had worked with some PC-based forms applications before, so I knew what type of function I was looking for. I scanned the forms into a PDF, and PDFfiller opened the files and allowed me to create editable fields on the forms which she then filled using your browser-based app. It got the job done! There were a couple times where she thought she had lost everything, but because of the automatic save function, nothing was lost. Unfortunately, I don't have any other immediate need for this, but I certainly hope you use this for promoting your product. I would have given it 5 stars had there been an apparent way of copying all the fields I added to one page and paste them onto identical subsequent pages in my document (you know the Government--lots of duplicate type information!). I had to create the same fields over about 8 or 9 identical pages on one of the forms. If I find I do have more use for this app in the near future, I will purchase it!

Faced with the daunting task of filling in the complete IRS 990 (due to the dissolution of a 501c7 non-profit corporation of which I was the treasurer) I have found that the PDFfiller program is a real godsend -- so much so that I almost regret not having an excuse to continue as a subscriber once the trial-period expires. But I will highly recommend the program to anyone I might know who regularly is faced with filing long or complicated tax forms.

Great customer service
I signed up for a subscription when I really only needed to use it for one day. I canceled the subscription but it must not have gone through because I was later charged after a month. I canceled again and contacted customer service. They said the first cancellation must not have gone through but then refunded my money. That is why I will definitely use them again in the future.

The only feature I don't see (maybe I've missed it) that would be helpful is the ability to spilt a document.Otherwise, it's super easy to use.

Easy to use and share documentation. Been an absolute godsend for filling in forms and applications. Probably won't use a lot as the requirements are limited.

Great service. I thought my subscription had expired but the tech support hooked me back up in a jiffy! I prefer to use PDFfiller program rather than the Acrobat Reader DC program. I will always renew my subscription in the future.

Completed what I needed done
Completed what I needed done. The reason for 4 stars is because you force people to sign up for a monthly subscription versus just charging for the one time use of the feature.
