I didn't know that PDFfiller would charge me a few after a lengthy form that I had to fill, I paid the fee and left a comment about the experience. I promptly heard back from a representative who made things right without me asking for anything. Customer service at its best!

I originally downloaded Adobe Flash Player thinking I could make my own PDS I was wrong it was I'm no help. Just by doing a simple internet search. I came across your website it's amazing. It does everything I needed to do and more so happy I found it! I'm a landlord and now I can send applications online and fill out leases online so convenient.

Just a few suggestions I have used some other comparable products, but pdfFiller offers the online hosting that makes it super convenient for the user to fill out the form without having to download the form first. However, I have a couple of suggestions. I wish the pdfFiller could have the feature to automatically convert the raw entry data (e.g. phone number 1234567890) into the selected format (e.g. (123) 456-7890), instead of asking the user to enter it into the specific format. I also noticed the accident that some fields will be deleted accidentally when saving the edited version in LinkToFill. It happened several times to me when I was editing my file. Not sure if that's an internal bug or an accident from the internet interruption.

Pdf filler is a company with a ton of integrity and cares about its clients Pdf filler is a really great company that has great morals. I signed up for the free trial and forgot to cancel before it auto renewed for 1 year. With Covid impacting my commission based business, spending 120 dollars for pdf software is not something I can afford at this time. The customer service rep Rachel not only refunded my purchase, but did it very quickly and professionally. Obviously I forgot to cancel and this company could of held my feet to the fire as it was my fault that I did not cancel the auto renewal that I agreed to and left my Google pay account for. However they did not do that. I will absolutely 💯 use pdf filler again in the future if the need should arise and would recommend it to anyone that needs to edit a pdf file in the future!
