pdfFiller scores top ratings on review platforms
I am very pleased with how easy it is to create impressive PDFs. PDFfiller offers all of the features that Adobe offers with acrobat - for about 1/2 the price.
The support team responded immediately when I had a problem (on a Sun night, I believe!) and the situation was resolved there and then. Impressive.
The only issue I have is that old documents that I thought would be saved are not. That is my issue, however, and not yours. Everything else is great.
Great job providing fillable IRS forms that I couldn't find elsewhere for this price. Difficulty in trying to return to find a new form after finishing one. New user & too soon for a survey.
PDFfiller is great if you need to edit/change PDFs
This software allows us to fill out and share PDFs, vastly cutting down on our printing/scanning song and dance.
No real negatives other than I wish it were free.
So far so good
I think the app is very good, well worth the price. Some features would be really good to have on the offline app. Only had it one day but other than that the editing tools are perfect for my business needs.
Easy to use
The frequently used function buttons are placed on a easy-to-find position. The interface is neat and clear which is user-friendly. It is easy and simple to use.
It was wonderful to use so I didn't…
It was wonderful to use so I didn't have to go to town to fill out the particular paperwork i needed to turn in. The only negative was I thought I was in a 30-day free trial period, and I was charged two separate charges, though they were very small, but yet I was charged.
Disappointed. I thought I had until the end of today to cancel the trial but got charged over $100 for using the service just to get matching employer funds for a donation.
I used the free trial to compile rent due ledgers for the ************** requirement. I did not cancel on time and was charged $180 dollars. I reached out to support and ****** returned my email within minutes. I provided my information to customer service specialist ****** and he fixed the problem. There wasn't any back and forth emails. It was straight to the point. Thank you ****** for being quick and professional.
