What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I write screenplays with a friend and when he works on the script he puts it into PDF file and I purchased this to be able to open files and make corrects, recommendations or add to the script. It worked great but there just are not enough instructions for me. It was trial and error.

Mostly good - had a little difficulty when the app decided I could only answer 1 category when I needed to respond to all 5 subcategories of a question. Also, messed with the date - it changed to a different format.

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.

I'm working on several files for which I need to be able to type in the answers as my hands have arthritis in them and that makes it difficult to write. The instructions could be a little clearer. To be honest, I'm a new widow and I wasn't thinking very clearly. I haven't taken the time to read the online instructions so my navigational issues are of my own neglect. I think you have a wonderful product actually.
