Nice applications, sometimes doesn't move real smoothe from one blank to the next if you do not need to fill in for that one it seems to get stuck and has a lag, but over all, nice program.

What do you like best?
I really like that PDFfiller is a very user friendly and employs a lot of the same standard editing tools commonly found in simple office software like Microsoft Word. It's a great step up from the standard Acrobat Reader and also has an easier learning curve than some of the more advanced Adobe PDF products. Being able to sign documents electronically is another strong feature.
What do you dislike?
When I edit a document that has more than one page, I am unable to perform a copy and paste across multiple pages, which is a bit annoying when trying to standardize items across one document. Saving documents is also very easy. We can save the document to any one of my computer folders or a cloud storage account.
Recommendations to others considering the product:
I think that PDFfiller is a very effective and easy-to-use PDF editor and converter. For the price and functionality, it's definitely worth checking out, in my opinion.
What problems are you solving with the product? What benefits have you realized?
Since we often deal with many types of text documents, especially Word documents, PDFfiller has really helped to enable conversions of Word documents to PDF, which are more ideal for certain things like printing. We can also convert PDF files to Word, which greatly reduces our need to perform time-consuming typing. In general, PDFfiller has been a great tool for working with PDF files with its intuitive interface and clear functionality.

Like most of the features
Like most of the features, I would like it if I could make boundaries and then just fill in the inside of the shape that I make like the old-school paint application.

I am a ******* Home Inspector and love PDFiller. I can do everything on my IPhone. I had a problem at first and had an online chat with ***, helped me fix a problem on a 4 point inspection and had it corrected in 15 mins. Once you learn your way around PDFiller it can save you lots of time.
