It's very good app. The cost for what it offers is alot better then having a Adobe subscription. You can fax and a whole bunch of things. It just made my life easy.

Fantastic customer service For some reason I needed this and only once. I got the free trial and then forgot all about it until $115.00 was collected from my account, shock horror. All I can say is you have fantastic customer service, I explained my situation and a refund was issued that same day. Both friendly and speedy. Ace by name and by character, much appreciated. 1 star deducted as I would have liked a reminder email when the free trial was coming to an end.
Sam
A life saver pdfFiller has helped me to make easier my load of work and without I might be stressing a lot. What I like most about this software is the ease of use, as an educator I need to use PDF's everyday and this software helps me a lot with that. The free trial is good but then you need to pay for another features.

Immediate Payment Refund Payment Refund Signed up for free trial with pdffiller and forgot to cancel. When I explained this to pdffiller my payment was returned to my account the same day.
Mr Aylward
It's fine so far, I double checked for accuracy off of the tax tables and it calculated correctly which is a positive for me and very helpful and a huge timesaver to know it is accurate and reliable
Susan K
PDF Filler is a great tool for me and my business. However, more fonts would be nice rather than the few that are available, around 10 or so. Also, if I can use art as a watermark instead of just script, that would be amazing. Otherwise, PDFFiller gets the job well done.

Useful for filling out applications. Its been so useful for applications that I'd otherwise have to write by hand. I have arthritis and writing information in tiny spaces is painful and there's never enough room for the answer. This has solved this problem.
