Its a good overall program although I had issues uploading my pdf assignment for school, and when I submitted it online, the pdf was completely blank. Not sure why this program did that.

What do you like best?
PDF filler is very user-friendly. My favorite features are that it saves your docs. This makes it easy to keep editing docs that you use over and over. Also, when you use the erase feature, it keeps the eraser on the same line, which I could never do on my own! At the end, you can download the whole doc, or individual pages, this feature really helps and saves time on splitting the document with other programs.
What do you dislike?
Once docs are ready, the loading time to save can sometimes feel slow. Also, uploading the docs can sometimes feel slow. This is not a deal breaker, but perhaps something that can be worked on. I think there should also be a feature where you can upload docs one after the other for the same session, and it will merge the docs (or ask if you want to) and edit them together. It seems right now we have to edit each separate if they are not already joined, save them, and then go to another program to merge.
Recommendations to others considering the product:
Have an option to merge docs, make speeds quicker.
What problems are you solving with the product? What benefits have you realized?
When I get contracts, most of the time they are not complete to be approved. This allows me to add extra details and even sign the docs. I like the stamp it adds to show when the signature was made.

PDF FILLER
I have used this for payroll and accounting documents at work and for personal use as well. I have not had any trouble using it at all.
The ease of use if wonderful. I love how much more professional documents look when using the PDF Filler than hand writing. That is another thing I love about this software - you can do it all on the computer/laptop and just attach to an email if you need to send it to someone or print for the files if that's what is needed.
I don't believe I have anything I don't like about it!! Who like hand writing forms??

THE BEST IN THE INDUSTRY
Very good product for the price. I highly recommend the annual membership.
I have used PDF Filler for many years now, it is easy to use and there are many features that it does have that I don't use. If you use this tool to the max, it will benefit any company.
Nothing really to mention about that is bad about this program....I know there are a lot of features that I don't use, that I would like to learn how to integrate into my company.

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.
