It was confusing. I had sent a rental app to a client and I didn't know where to get the reply. When the customer called me she said she was unable to send it. I eventually found it on the PDF Filler site but couldnt do anything with it. I then realized even though I thought I subscribed, I apparently did not. Found that out when I clicked "done" and suddenly the prices came up. Very confusing way to do business.
Ted K
Easy to use, unlike other fill and sign apps, it can tell the right size text. It can tell the what parts of the document requires the text. The variety of templates to use for common forms needed for most people. Also a generous 30 day trial A ++++
Rebecca O
PDF Filler is great. I started with the free trial, then went to the pro, but now I've switched to Basic. I got this for signing contracts on buying and selling my home. Awesome!
Melanie C
What do you like best?
I like the choice of fonts because one can add changes or complete empty fields to a pdf and by using a different font from the original text it is clear that the additions are different from the original.. Also I like that one can add circles, check marks, "X" to a doc. And can erase portions of text.
What do you dislike?
I dislike that you have to pay extra to add or subtract pages from a pdf.
What problems are you solving with the product? What benefits have you realized?
My hand writing is very poor. So I use PDFiller to compensate for this deficiency..
Mark Flynn
Phenomenal Customer Service Due to the pandemic, like a lot of people I was forced to work from home. My employer doesn't adequately support us in this task and so one day as a matter of urgency I started the free pdfFiller trial for a month. I set a reminder to cancel my subscription but I didn't complete the cancellation. When the annual subscription fee was taken from my bank account I was devastated, it's a deduction I couldn't afford and my employer would not reimburse me. The team at pdfFiller were amazing. They ensured I successfully cancelled the subscription and they also processed a refund. The speed of response was phenomenal, their empathy towards someone who genuinely could not afford the subscription was so appreciated. Their customer service is like nothing I have experienced before. Keep up the great work.
Deirdre Montgomery
What do you like best? PDF Filler is extremely easy to use and navigate. I've never experienced any lag or difficulties in using the software. Signatures are easy, dates are easy to inpute. What do you dislike? You don't get to really choose where files are saved when you download them. What problems are you solving with the product? What benefits have you realized? I've been able to easily fill out and save consolidation agreements, settlement letters, and anything else that I need and don't have time to print out and sign just to have to scan it in. It's definitely a time saver!
Nicole Vorron
I filled out forms before purchasing app and thought it was saved. After I purchased the app I could not find my document. I texed with a customer service rep, he was no help and quit the communication.
Douglas T
What do you like best? It is very helpful to be able to fill pdf's in. It also saves paper and time. I hate having to print a form out, fill it in by hand and then scan it into the computer just to turn around and email it. With pdfFiller I can do the work on my computer, it looks professional and then I simply save it and email it. I also like the fax option. What do you dislike? Sometimes I have a little trouble getting everything just where I want it. But the more I use it the easier it becomes. I feel that I will like it even more the more I use it. What problems are you solving with the product? What benefits have you realized? I am solving the wasted paper and time. I am able to keep everything electronically. Forms look more professional. I do not have to pay a separate service for a fax line which I only use a few times a year, I fax straight from pdfFiller.
Susan Spencer
I needed a HIPAA compliant PDF editor and found this one. Lost the document I was working on but was helped by chat and got it back. Very relieving!
