See for yourself by reading reviews on the most popular resources:
I am only done with one of two multi paged forms.I was very thankful to be able to fill out some very long forms with a computer rather than free hand.

First time user needed. I needed to use live chat to find the forms I needed for the IRS.The videos were helpful along with the live chat.I can see other instances when this service will be helpful.Great experience.

There are some things that could be more user-friendly or convenient but overall it is very effective and useful as a tool for creating and modifying documents. The "preview document" is never accurate, and the ink looks faded after it is scanned in as a template.

Had everything I need for editing all…
Had everything I need for editing all my pdf files. And the customer service was one of the best I have ever experienced. So efficient and friendly

Simplified accuracy !
pdfFiller simplified and shortened the length of time; when I needed to complete filling out pertinent documents.
My first experience with pdfFiller was when I had to do taxes. All the technical difficulties with filling out tax documents no longer existed.
There are no Cons to specify, except my fears that this app is a "too good to be true" app. If you knew that before this app came along, PDFs were untouchable and un-editable.

Great app, but even better customer service. I needed to cancel my membership for financial reasons, but I failed to do so before it renewed and my bank account was drafted. I submitted a request through the website for support and requested a refund. *** replied via email within an hour and had already issued the refund. Clearly they care about their customers, provide easy communication options and have fair policies in place.
