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.

Had one problem a long time ago, which was quickly resolved by a PDFiller staffer.

Support is good but last release is bad I am really fond of their support team. They are very friendly and provide all help the can. But that's not enough for good product. Support can't fix bugs or make it good for tablets. Try harder.

I was very impressed with this web-based PDF editor Overall my experience has pretty very positive with PDFfiller. My colleague recommended PDFfiler as I needed a quick way to sign documents while on the road. PDFfiller has all the features I need, even with the free version of the software. I think to take this software to the next level, the developer should create browser plugins to sign documents without having to upload them to the PDFfiller website.
