What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
It would be much more efficient if multiple copies of the same form were filled automatically with the information entered on the original. Completing the documents should be quicker and simpler, no reason one has to play with font size and trying to pin point the location of the mouse to ensure proper destination in the field of entry on the form.

Work and Study Budy Overall I love the app and all the features it offer! The benefits totally outweigh the cost. Amazing app! What I like most about the feature is I can use it both for work to fill out pdf files and for my personal studies where I can write notes, comment, add highlights and more to the file. What I least like about this is it can be a bit pricey to maintain especially if I were only a student. But good thing I am also using it for work so I can really maximize its use.

Excellent customer service. Keep it up. Excellent, excellent customer service! I contacted the company because I was charged a subscription fee which I wasn't aware that I had not yet cancelled. The customer service representative called Anna, I believe, immediately informed me that the subscription would be cancelled and an email to that effect was sent to me. I was also informed that my money would be refunded shortly....and indeed, it was returned to my card in 48 hours. Although, I don't have need for their services at this time, I would definitely use them at a later date, should the need arise.
