I was very upset that I wasn't told I'd have to pay until after I'd edited a very long file, but customer service gave me 30 days free when I brought this to their attention.

Very easy to use. I tried several free PDF services for editing PDF documents and I was totally lost. PDFfiller meets all my needs. Is reasonable in cost.

Decent, though the affiliated linked program options which supposedly come with the upgrade purchase don't seem to work / or be actually as advertised.

Great product to add a professional look to your completed documents Adds a quality appearance to my work. No more manual handwriting ugly forms. Once the user is able to follow the print/save process the end product is quickly achieved. Quality finished product when using PDF-Filler. The software easily converts rough looking hard to read forms into easy to follow wordsmith quality documents.

It got the immediate job done but there were a few hiccups. I don't particularly like their way text is displayed in the larger fill-in fields. The form I was filling out was very complicated and required numerous references to a "Remarks" section at the end of the form because there was insufficient space with the numbered questions to put complete answers without overwriting onto the next numbered question. Consequently, the Remarks section was filled necessitating a separate attachment to contain all the remarks. In the remarks section, I cross-referenced to the numbered question for clarity, e.g. "Question 12(b)..." When I viewed the form on the screen the formatting looked fine but when it printed, the "Q" in the word Question was on one line and everything else "question 12(b) was on the next line. I would like to know how to avoid that issue in the future.

I've been using PDFfiller regularly for over 2 years now, and it works wonderfully. I'm able to upload documents, add fillable lines, and get electronic signatures seamlessly. Customer service is also great - prompt and friendly in attending to any questions or issues. Makes running my business that much easier.

Needed something to fill out a form in… Needed something to fill out a form in a hurry - it did recognise the fields, that's a plus compared with some others, LOL. Wasn't looking for any fancy features like faxing, but did the job. May only cancel IF I don't use it that much.
