An excellent program, my only gripe was/is after paying for this program, I began to experience unsolicited X-rated and non-X rated ads. And, interference using Safari on an Apple PC

this is the only application that I can fill in the Appraisal forms on my Mac Pro. the other softwares are just for Windows based programs. This does what the others do for less than half the cost.

PDFfiller came in very handy, especially with the ability to fax. Recently, I had to complete documents on behalf of my mother after my father passed away. I was limited because she had no internet, so I purchased a portable MIFI and once I realized that I could fax with PDFfiller, this eliminated the need to spend money on faxing & postage.

great product. a bit pricy for the monthly subscription. charging by the document would be better for a person like me who only needs to use the service occasionally.

So far every form that I need was available. I have spent hundreds of dollars a year in other software, staff and time what PDF Filler now does for me.

Very helpful tool for 1099. How do you auto populate though. I find it tedious to manually type the same info over and over. Still WAY better than the alternative though. Thanks.

What do you like best?
The ability to edit practically any document, within reason. As a Finance professional, it's much easier to add a JPEG of a signature to hundred of checks rather than signing them by hand. My carpal-tunnel free wrists thank you!
What do you dislike?
I don't have any negative comments; everything that the program promises, it delivers.
Recommendations to others considering the product:
It's a great value for a relatively low monthly cost.
What problems are you solving with the product? What benefits have you realized?
It allows for rapid addition of signatures to checks, contracts, affidavits, etc.

What do you like best?
I like PDFFIller because it always works, unlike some other PDF tools I've purchased in the past. PDFFiller is my goto tool and will become my exclusive tool once my other package expires.
What do you dislike?
There's a little confusion when saving to my Google Drive. Now and then, the file can't be found there when on my phone.
Recommendations to others considering the product:
I've also used Ecopy for several years and just find PDFfiller to be more user friendly and stable. As I said, it's my goto PDF tool.
What problems are you solving with the product? What benefits have you realized?
I fill in forms, I create forms listing medical issues/histories, electronic signatures are always handy. I also convert to Office Documents if needed.

What do you like best?
The fact that I can pull internet forms down into the software and then sign them electronically is a life saver!
What do you dislike?
I really haven’t found anything I dislike about PDFfiller. It’s quick, efficient and super convenient.
What problems are you solving with the product? What benefits have you realized?
It solves the problem of having to print out forms sign them, and the rescan them to send them where they need to go.
