pdfFiller scores top ratings on review platforms
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.
I spent approx $70 for PDF Filler, could not find a page rotate icon when I really needed it, then a screen popped up that I would have to spend $120 per year to have this additional function. I was in the midst of needing to reorient some legal documents so paid the additional money. I find this to be less than fair business practice as when I signed up there was no clear breakdown presented on the functions available for different costs.
so far so good, very easy to use. The only issue is I can not verify my office # as I do not use a CELL phone. CAnnot receive SMS text to verify my tel#
Very helpful tool, was able to do all that I needed using it. Rate 5/5, recommend to everyone who needs to edit/sign PDF files and quickly share them.
Easy to use!
I found the system very easy to use and have only scratched the surface. Converting documents to an editable form was easy to do and the system made it easy to find available PDF or other formatted versions online.
Saving different versions or templates was a bit of a challenge but that was easily remedied.
Easy to use and very convenient.
Easy to upload and fill out any document. Saves as PDF or prints. Even has some tax and medical documents that you can download right from the site. Very convenient.

I subscribed to a trial period for the PDFiller product but forgot to unsubscribe when the trial period was over. Once I realized my error, I contacted the company and explained my error. Katrina in customer service had my refund processed within minutes. Thank you Katrina and, as I promised, when our company is financially able to afford this wonderful product, I will once again be a customer. This experience earned 5 stars because of Katrina's kind ear and quick action. Thanks to you, Katrina, and whoever trained you in customer service protocols.

Good and easy to use except not easy to move things around once you've put it somewhere, and also not easy to put the text box right on the line that you're supposed to be filling out
What do you like best?
We have used PDFFiller for years. I like the ability to use editing tools other apps charge extra for. The ability to use the mobile app was especially useful when we were in a bidding war for the purchase of our home. We were able to edit and sign purchase agreement on the fly.
What do you dislike?
User interface has not been updated in a while and feels a little clunky.
What problems are you solving with the product? What benefits have you realized?
We have clients sign documents and contracts. We are able to edit PDFs directly rather than scanning or retyping documents in a word prove easier.
