See for yourself by reading reviews on the most popular resources:
I wanted to be able to duplicate a filled form and make a couple of changes. Then save with a new name. I did download and rename before I did this. glad I did. PdfFiller overwrote the file. All is well since I downloaded the original.

The program interface is OK but it could be a little more iterative. A form I was completing for the TSP TP77 and the TP76 did not place the letters and numbers (characters) in the exact center of each box making the document a little harder to read. I know this for sure because I have completed the same document using TSP website filler with the document are available. This would be easy for the company to fix this but they check their forms before making them available. But the overall online forms filler program works well and saves completed forms easily and has a generous library.

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.

I had an issue that was my fault and it was taken care of immediately. Even late at night. I was very worried that there was no phone number or email to contact them but they replied quickly through their live support and took care of my issue and fully refunded my money. Thanks.b

What do you like best? The app notifies me of when someone fills out my form. What do you dislike? The integration from the link in the email to the app on my phone. For some reason, there is a disconnect. Recommendations to others considering the product: If you have customizations and processes you wish to conform E-signature function in your documents, PDF Filler is a great tool. Great for contract-heavy and approval-required documents for our business. Great for folks who have medium to advanced level of word processing abilities and technical capabilities with graphic apps. If that's you, you will be a quick study. If you find it dificult to work in a Word document or Powerpoint or other types of programs, this app will have a learning curve for you. What problems are you solving with the product? What benefits have you realized? I cut down my use of paper and ink. I save time by modifying PDF's within the application. I can merge multiple documents. It has streamlined processes in our business to get paid faster and run more efficiently.

I love the fact that a function stays the same until you change it, eg. a font size and format. However, I would like the option to use all the Fonts that I have installed on my own computer. When a page is duplicated, I'd love it if the 'changes' made to the original using pdfFiller, could also be duplicated rather than simply a duplication of the original document. I also can't seem to find a way to cut and paste text to apply it in a different area of the document, which means that the process of replicating a change is more time-consuming, but this could be my current unfamiliarity with the software. I was impressed that within a couple of hours of use, I was offered the option to attend a webinar to improve my understanding.
