pdfFiller scores top ratings on review platforms
I was disappointed that the orm did not perform the calculations called for - I had to do them off line on a calculator. Did I miss something? Type size was very small and I did not know how to change it.
The form I found on PDF filler was the closest to the form I needed. I had looked at other web sites but nothing matched my needs.PDF filler had the most appropriate form to suit my needs
I have used PDF filler a couple of times and so far I love it! Just a little suggestion, maybe you can add/give the option to be able to change the size of the fonts without having to add a text box where there is already one to fill (does it make sense?). Thank you!
Great pdf editing software
PDF Filler is an awesome piece of software. It is so good being able to edit docs online and save them without having to worry about retyping information because the pdf provided was not able to be edited
There is no version history which means if you make changes to the pdf you can backtrack to an earlier version unless it was saved separately
It opens up pretty slow, and everytime I open a document the zoom is set to 134% and I don't know how to set it to 100% other than that the pdf filler is easier than others I've used and the other features work good.
pdfFiller has wonderful support. You can email them or use a chat feature. From the chat feature, I was able to do a remote session through zoom to get my issues resolved quickly. Through email they always respond within 20 minutes. Great customer service!
Easy to use and works perfectly for my needs
finding this a very useful and easy system to use - meets my requirements for simple PDF editing brilliantly.
I love Pdf Filler. I have tried ten different products similar to Pdf Filler and none of them had the features, functionality, utility, intuitive interface, and price point. I tried ADOBE and absolutely hated every moment. I cannot tell you how happy I am with your product!!! We have streamlined our HR onboarding process and our clinician credentialing process. Thank you!
The product is very good and it works very nice and...
The product is very good and it works very nice and it's very easy to comprehend how to use it, but the way you have the purchase setup I feel is very misleading I signed up for the month the month payment and you took a full year out of my account I did not like that that is why I would never recommend your product to anyone want to use because you can really mess up a person and you could be taking money that they could not have to be taken at the time. You need the fix your payment process area or you will lose other customers like myself because I did report it to the Better Business Bureau cuz I did not appreciate that.
