With the exception of the scam you have going to get people to sign up for your service... (i.e., On a holiday I came into my office to get work done quickly so I could then spend time with my family. I was soo pleased with your service as it let me upload a document and seamlessly edit it for 2 hours and the peace of mind that everything was working properly as your program continually provided feedback saying that 'all changes have been saved'. Then when I finally finished, after triple checking my work and feeling thrilled that I could go celebrate the holiday and be with my family, I selected the big bright button that says, Done!. And only THEN, after 2 hours of work, did you tell me, there is an error and I need to sign up for your program. You should be ashamed of yourselves. I was so excited to tell other people about your program and how well it works. After being scammed, ripped off in terms of money and precious time, I won't be telling anyone about your service. If you prefer to keep me as a happy customer, perhaps you will find a way to make up for this inconvenience (e.g., give me a discounted membership, upgrade my membership, some other kind gesture?) and correct this misunderstanding that you are covertly enticing people to use your program with an inconsiderate scam. I'd love if you followed up with me about this survey. Thank you. Sarah

This is easy to use. Since I have only one document to process and a CPA does my taxes, the cost of month-to-month seems high. I do hope it's easy to unsubscribe. I can't stand the way peoplefinders tries to undermine one-time usage. So thanks for your clarity and integrity.

What do you like best?
I use PDFiller constantly. In some ways, better than Acrobat,
What do you dislike?
Price of a subscription. (Being forced to write 40 characters or more is absurd.) Also, the survey is too long and time consuming.
Recommendations to others considering the product:
Would be helpful if png's were accepted and converted to pdf's.
What problems are you solving with the product? What benefits have you realized?
Had one problem a long time ago, which was quickly resolved by a PDFiller staffer.

Very helpful in my law practice. Ease of filling out a variety of documents. Easy to use. I like being able to switch from the wizard option to the self fill-out option. It is usable with all the legal forms I fill out. I do not like how I cannot change font size when using the wizard to fill out form. Sometimes I don't have enough room in the space to type what I need. I also don't like how you lose what you have filled in if you switch from the wizard half-way through.

Ease of use is what attracted me to program. I use it to make fillable forms for work (forms already made, need to be made fillable). Is cheaper than Adobe Pro and is better in my view.

Bravo! I was just on the phone and wrote back to congratulate the customer service rep on my call. I was very nervous about making sure my document was sent properly because a 5 year deal is riding on it. She helped calm me and understand things were handled properly. Bravo!

Excellent programme Excellent programme, does exactly what you need it to. I'm very satisfied with it.The only reason I didn't rank it 5 stars, was because it is slightly slow to use, in that there are a lot of buttons and windows.It could be made to be more intuitive, and more straightforward.But nevertheless, it does do what I need! So no complaints.

I had a problem with PDFfiller and sent… I had a problem with PDFfiller and sent a mail to support. They replied within an hour or so, really excellent service. I live in South Africa where government support is poor at best. I downloaded the form, filled it in online and printed it without the slightest hitch - it just works!Roland, Johannesburg.
