I signed up for the free trial and was… I signed up for the free trial and was able to amend 2 documents with ease.If I had the kind of life that required me to need further amendments in this way, this service is absolutely one I would use. Thing is, I just don't, so I didn't sign up after the free trial! Had a little difficulty cancelling the subscription, but honestly - I think that was 'on me', I just wasn't entirely sure what I was doing.However, it's a great service and the company responded to my concern when the subscription fee was taken by emailing me back and confirming that they would be refunding the cost. So, I think you can trust this company.

easy to use but i don't use so much its really a good app, but at the same time it does not fix all my needs, but i usually do need the app when i have to edit some pdf file, because i feel its easy to use, very intuitive, but i don't use so much the signature features should be improved

I am very impressed with PDF filler and its features. i am not the most computer literate person and i do have a bit of trouble navigating around the program so a demo of some kind would help me a lot if there is one that i can watch. I guess its just a case of playing around with it but there's probably loads of easy shortcuts that i could use if i knew about them .

This is one handy app This is one handy app! I'm constantly having to sign this or sign that but pdfFiller makes the process so simple and seamless. Gone are the days of printing my doc, signing it, and then scanning it back to HR at our corporate offices. pdfFiller has saved me a ton of time! I love it1

So far so good So far so good, I use Adobe Acrobat Pro DC at home and at work, I am still on my first day of my 30 day trial of PDFFILLER but I'm impressed so far. I particularly like the library and search features. More to come as my experience develops.
